Wait till the Engine is cool. Lift the vacuum hose out of the way and reach behind and you will feel the wiring. Pull the plug. Use a 1 1/16 thin walled socket and a short extension. The sender will come out fairly easy. Make sure you replace the screen. I was able to do this easy without removing anything at all.
Just wanted to say thank you for youre video very informative and straight to the point people like you help the working class folks that can't afford a shop .keep up the good work there are so many people that rely on you in there time of need . Mine quit today at 3 am I had pulled over and removed the oil fill cap and verified oil being pumped up closed it up and drove to work and home before changing it took me about 25 30 minutes it is very difficult to get to but I did not unhook any lines just removed the plastic cover and used a small tbi unit hold down bolt off a 90s Chevy to get the screen out it was plugged solid .
After my mistake on spending 500 bucks on a new oil pump, my "professional mechanic" did not fix this problem. Later i saw this video, it was just a blessing to the headache i had on figuring out the problem. As mentioned in this video, it was the filter itself. Many props to this gentleman. Thanks
Excellent video, now just dreading doing the work 😂. Thanks Tim, for telling the truth on what a pain in the rear this job is.
That little filter should be included with the sensor! THANK YOU! THANK YOU! For your video. I’ve replaced two sensors and nearly pulled the oil pan before checking CZcams one last time. Luckily I found your video. My Yukon had very low to zero oil pressure on the gauge but didn’t knock or tick throughout the rpm range. I pulled the sensor and filter popped in a new filter, buttoned everything back up, hit the switch.... 50 psi! THANK YOU!
Did this with my 08 Suburban. Got my hand stuck, not much fun but gratifying when complete. Time for a bath.
I just had mine replaced....twice!
Remember to REPLACE THE SCREEN FILTER AT THE BOTTOM OF THE SENSOR! Some mechanics will say it doesn't have one just so they don't have to pull it out because it's a pain in the but to remove!! Nevertheless it is there!! Great video!!
Good work. Always nice not having to pull the intake and losing half the bolts. This way you can just drop a few sockets down the back of the engine by the time you're done.
haha, I edited that part out.
Kinda funny Down Under talkin to Up Yonder.
Indeed
Just did the same thing you did in the video and it’s working fine now!! Thanks for the tip 🤙🏼🤙🏼
Great video! I just did this on my 2007 GMC Sierra and it’s a lot better than pulling the intake. I also found out that using a wall anchor and screw for picture hanging is also a good way to pull the screen filter. Just put the anchor in the hole after removing the sending unit and finger tighten the screw and remove. It came out quite easy. Thanks!
Thanks for the video! I just fixed my oil pressure sensor a few minutes ago. You helped me save over $150.00!!
Awesome!
Really appreciate your video! I've watched so many I'm a bit depressed. I have the sensor and the screen and need to just do it. At 70 years old I don't bend in places I used to but am willing to try again. Used to make a living as a mechanic but they make vehicles too complex these days. Anyway, thanks for your video which is very straightforward and calming! Moreso, thanks for your patient encouragement! Be safe...Tom
Thanks Tim! This video is very informative and helpful. You inspired me to attempt my own repair. I was able to change my OPS on my 2007 Yukon 212,000mi. Glad to see oil pressure again!
Mm
K
Was it running about 20 to 30 on your pressure guage before you changed it?
WOW!! This could be HUGE! I have watched my engine oil slowly drop over several years to maybe 30 LBS while hot and driving, and 20LBS at idle with 300K on engine however, no noise and engine runs great! it is a 2006 LQ9. If it is that screen I will be downright giddy! All highway miles and regular oil changes with Amsoil. THANKS!!
Hope it is. Throw the screen away.
@@ThecardoctorTV Appreciate that however, i pulled the sender and there is NO screen! There is what looks like a metal tube up to the base of the sender (female side) threads, with a smaller hole at the bottom, very strange. So much for HOPE.
@@davebarron5939 I believe the screen is there to protect the solenoids in the AFM "VLOM". I don't think your 2006 should have that system, you lucky devil.
Thanks made life a lot easier for me. My gm dealer wants 2500 dollars to fix it.
FYI. I did this with success on a 2010 suburban.
Another great tip. Something I've noticed that really contributes to this, at least in my experience, going to long on the oil changes. have noticed this a lot when people run synthetic oil, they go way to long, the oil gets to thin and dirty and it plugs up those screens and the sensor. But something else I've noticed, on the engine with the active fuel management that have the oil consumption problems seem to be worse for this.
kenman1717 plugged screen=burnt out engine.
Tom OConnor have seen that too.
Totally agree. This guy keeps the oil super clean and it apoears to be strictly on the electrical side. 125K is actually a lot of miles up here.
warriorpluto if you have good oil pressure, not using oil, no noise and do your oil changes when you should, I wouldn't worry to much. and something to keep in mind, warm your truck up for about 10 mins or so before draining the oil on an oil change it really helps cut down on sludge build up. have pulled engines apart with 300000kms on them and the lifter valley had over an inch of hard caked on sludge and it was do to many cold oil changes.
Most places like walmart, jiffy lube and others wait for the oil to cool down for an hour before they change the oil.
Thank you for your help. This quick fix made my day, was able to fix the problem in about and hour. Please keep up the videos
Thank you. Super glad this helped. Blessings
Thanks for showing the parts, and real-world removal tips. This will come in handy and my oil pressure seems to be slowly trending lower.
Hope this helped. Blessings
Thanks you made that issue clear enough for DYI...
Hey .. Thanks a lot, this tip saved me some time; always looking for these kind of videos. And I certainly appreciate your simple and to the point demeanor, the explanations and directions are spot on.
Thanks again...
Thanks. Super glad it was helpful. You take care!
Great information Tim. I have a 2003 Tahoe 5.3 eng with 91000 mi and have not had any major issues with it yet!
Hope it keeps on providing trouble free service for you. They are a solid vehicle for sure. Take care
Change your oil every 3,000 miles because the greatest with 5.3 is people not changing the oil like they should and lifter start tapping because the oil pathways get clogged with sludge.
Thank you so much for this video, I fixed my self and sage 300$ in repairs
Dont use ac delco oil filters. The oil pressure in my z71 dropped out and I thought I had a real issue, just needed an oil change. I switched to mobile 1 filter and it had been awesome. 10 bucks but better than ac delco.
Nice video Tim! Yea 129 psi with the engine off I'll play Las Vegas odds it's electrical...call me crazy! Keep the videos coming!
Pretty good odds on that one buddy. If I wasn't making a video I would have replaced the sensor and filter without even looking at the scanner. Pretty common issue and the engine wasn't knocking so it was a good bet. Thanks for dropping in.
Enjoy watching each time, Thank you!!
I have an Escalade, which is GM but it has a bunch of random readings. It goes from no oil pressure, which says
- - - PSI, to 190+, then down to 0 and when it does that I’ll get the low oil pressure (turn off engine) warning and dinging sound. I haven’t tried the to replace the sensor or screen yet, but I’m also getting the same codes and will be replacing it ASAP. Thanks for the video!
Thanks nice way of explaining definitely how to check that it is the sensor and not the gauge
Very nice video and very informative! Thank you for taking the time to make it!
You did not mention the issues the 5.3 has with the oil pump pickup tube o-ring.. where pressure starts normal and as it gets warmer it continuously declines to zero or almost zero... I have found this as a professional in shop mechanic to be more common than anything when it comes to abnormally low oil pressure readings..
The Oil Pressure Low Message
Is a GM defect on the oil pump pressure relieve valve
plunger that gets stucked.
They should make a RECALL of all vehicles that have this
problem, It is very costly to replace the oil pump for something so small and
simple.
Envoys, Bravadas, Trailblazers and a lot of other vehicles.
There should be a Class Action against GM for this.
The problem is that when the valve is defective the computer
incorrectly senses Low Pressure. That’s why when you step on the gas, the low
pressure message disappears!
In other words…is just a momentarily lie from the valve that
makes the computer think that It has no oil and your car stalls trying to
protect itself.
This is how I solve it “momentarily” after I did all this…
Changed the oil sensor.
Flush the engine with Kerosene
Replaced the engine pickup tube.
Clean the throttle body (was dirty)
After all that, I was about to give up and sell my Envoy, but
I finally found a video where it was explaining the oil pressure relieve valve
defect
What I did, was to change my engine oil to 40W and use LUCAS
oil treatment And Voila! The engine oil pressure went up and the low
pressure message has disappeared. (up to now..knock on wood).
I wish you all luck.

good day sir, from the philippines. i would like to know if there is a problem with my oil sensor if it slightly fluctuates during idle? should i worry about it?
No chevrolet is gonna fluctuate as the oil pressure changes I wouldn't worry about it
I have a 04 envoy xl. on vacation far from home where I do my own maintenance. the pressure went from normal to 0 parked at Walmart. never had this happen before. it would be a long tow but thanks for this video.
Hello brother I have a 2005 gmc Yukon Denali my reading oil pressure reading stays at 0 I have been driving the truck like that for a while I have no engine codes another thing is there is a problem with my cluster my milage is ghost and prnd123 are barley visible everything else on the cluster works other than my oil pressure gauge stuck at 0 just need some input before I start spending money on parts
Thanks for the great information! I'll probably be changing mine out in a few days when I can get some time!
You doing very good job 👍👍👍👍
Nice video 👌👌👌👌👌
You very good teaching good teacher 🤠
Thank you so much I watching each All video 😊
This is Rana Hamayun from new York long island
Thank you so much
Does anyone know if a faulty oil sensor will cause a know start condition
I'm not really seeing the exact problem that I'm having anywhere. I have an 06 silverado with 4.8. At idle, it shows 80psi, under load, it shows 0psi. There doesn't seem to be anything other than 80 or 0
Awesome. Worked just like you described! Thank you much
Thank you this helped
FYI look out for plastic weather seal on connector for oil pressure sensor.
When I removed connector from bad sensor, seal fell off connector.
After new sensor was installed and connector reconnected, seal was discovered under truck!
Great information that will save me some time and money. Thank you for your work!
Great video, thank you for doing this! Informative and saved me a lot of work, as I did not have to pull the intake manifold as the manual says.
Great! Glad it helped. Blessings!
Shouldn't the oil pan light come on the never seen it I've been at least 2 qts low ive been low before
I had same problem. Changed oil pressure switch with no fix. Added STP oil treatment and problem went away. Apparently 5W-30 is too thin. You need a thicker oil if you have high mileage in your vehicle.
m looking at 05 Yukon with this problem, I will go for it . It's very reasonable
Thanks, Tim for this great info. But what about a 2013 GMC Serria we did the sensor and filter change but the pressure came up for a second then went back to 0 pressure what can i look for now ????
I wanted to see what the oil pressure would be on a hot engine at idle?
What if i change the oil pressure sensor and still shows low oil pressure?
They should make a relocate kit. Maybe thread a high pressure hose in the back and locate the sensor on the firewall.
I understand they do for the corvette
Found out today my oil pressure sensor switch is broken giving no reading. On the way to work the oil light came on saying pressure was low. The engine could this be a malfunction
I have a 2003 Chevy Silverado 5.3 and my oil pressure went all the way up to 80 so I switched the oil pressure sensor and it was working fine but two weeks later my oil pressure went down to 0 and I got the low oil pressure sign. Do you think it’s still the oil pressure sensor or could it be something else?
Have you tested the actual oil pressure?
What a hassle just to get to an oil filter screen.
So I have that issue but I've had the sensor&filter replaced twice. Could a oil pump or o ring on the oil pick up tube cause the same issue
Nice fix without any collateral damage.Helpful comments below from the viewers.
Some pretty smart viewers. I sure learn a lot here. Thanks for dropping by.
The other thing that seems to go on these when they show no pressure and has no pressure is the oil pump relief valve sticks or the O ring that connects to the oil pump to the pickup tube splits.
Good call. I should have mentioned that. I kinda glossed over actual low oil pressure issues.
I dunno what the heck GM did but alot of those LS engines have the sudden loss of oil pressure. Its good just the sender fixed it. Those are cheap these days too they used to last forever
Mine just did loose alot of psi the other day while riding thing was it happened about 300 miles after I did a oil change (new to me vehicle so It was the first change that i have done to it) but out of nowhere it now idles at about 10psi and right about 20 when cruising before it sat right at 40 when riding and about 30 when idle, but only when the motor becomes hot the pressure drops, any ideas , I put 10 40 when I changed the oil, and just did another change yesterday to 20 50 and still when hot loses pressure any idea's?
@@sexdrugsrocknroll420 what did you find out? Ive replaced the sensor and screen in mine. It sits around 20 at idle and still throws the code
@@TDIETZ22 it's most likely the crankshaft bearings going out is what I've narrowed it down to
Dinner engine swap for a block block on a 2009 GMC Yukon and still not get no oil pressure the build-up to a 40 then it drops down to zero then the truck shuts down after about 5 minutes any recommendations what I should do next
Excellent description
Do all these trucks have that screen on them? I have a 2000 silverado and couldn't pick it out maybe didn't go far in enough.
Mine went from normal to zero overnight. Changed both filter and sensor but nothings changed. Still a daily driver for over a year and drives fine. Any ideas? Perhaps the other end of the sensor. Any idea where it connects to?
nice vid. you deserve 200,000 subs, not 22000. you exaplain very wel. greetings from mexico.
Thank you, I agree on the 200,000 number haha
Will Mobil 1 oil filter cause these to read just about 0 oil pressure on gauge and warning light on dash? Guy I helped out wanted to use 10w-30 (5 qts) Lucas (1qt). Did it started truck sounded fine ran fine jumped inside and almost died when saw gauge at o and warning low pressure. 05 sierra 5.3.
You don’t have to remove all that just to get to the sensor... Just remove the comer and reach behind there and take it out... You can’t really see it, it’s mainly feeling your way around it... Good video but unnecessary removal of hoses... I just did this job today on my 07 GMC Sierra 1500
Great video. Thank you. If you don’t replace what could possibly go wrong other than not being able to visibly read your gauge. ?If we keep up with oil changes etc. ?
I'd get a vehicle towed if it had this problem because if the warning is real then your engine can be destroyed within seconds after getting the warning. Unless you have the tools to diagnose or fix it right then and there, but definitely don't drive it and tempt fate. Very expensive gamble.
Bull scrap Ben drive my 91 chev for years no oil pressure
Question... I got my transmission rebuilt.. Got it put back in and then I started my truck (2008 chevy Silverado) drove down road and there was no oil pressure at all. Replaces the screen and sensor.. Still nothing. Can the gauge be bad?
So when I start up the oil pressure sits at half but drops to a quarter when truck is warmed up and driven a bit, parked, it drips a few drops overnight.
Bad filter, wrong drain plug, rear main, hoping not the rear main
So I bought a 2003 Cadillac Escalade and it has a traction control disable light and also it has an ABS light come on the petals kind of soft. where should start looking? I kinda want to save money and do it myself.
My Sierra 4.7L lifters start ticking when the truck is idling. But once I drive it around like normal the ticking goes away. Could that have something to do with oil pressure?
If it's not clicking when you first crank up cold start and it's reading low oil pressure sensors r2 blame
Sure twice once on the road truck was acting up pulled over found out i was at least 2 qts low oil pan light on dash never lit, another time i took it to the dealer for oil change there was no oil on dip stick yet the idiot oil pan light never lit---but im pretty sure the engine check light did light, fyi the oil pan lites then goes off after the start up lites but I've never seen oil pan light even when i knew it should. Could this be the reason so many are having oil related problems, of course the 5.3 uses /burns oil,the oil pan light is extremely important for this reason alone( its about the early warning before engine check light comes on, hope this makes sense
Remove the little bracket and u will have access even without removing no lines and hoses at all saves alot of time
What about if it reads about 20 psi running and it has a ticking noise and it gets louder as I keep driving? Signs of a bad fuel pump? Mine will have a good pressure in the morning but while I keep driving it goes down and I get a ticking noise or lifter noise
Replaced my oil sensor still getting the p0521 code pressures still showing between 15-20psi at idle and 30 to 40 while driving after replacing both the screen and the sensor any ideas on where to go from there
So I jumped the grey with the tan/black wire and it still reads 0. In fact I get 5 volts from the power and the other 2 read ground? Any idea where to go from there?
The second you said disconnect the fuel line i called a mechanic
I am not risking breaking something
this video also works for the 2007 hummer h2 6.0 liter, the only other thing to do is there is another electrical connector right beside the oil pressure switch on the passenger side, i had to disconnect that as well in order for the socket to fit on the oil pressure switch, otherwise it wouldnt fit.
Excellent. Thanks for the additional feedback.
I've been wrestling this problem for a year now and have replaced sensor, screen, and oil pump . And still having the problem . After a flush and fill runs great for about a month then bam right back at it :( any other advise
I like that signal circuit integrity check nice I wonder what a bouncing Guage means bad power or ground or open short of some kind
I agree a good tip, getting it jumped from under the hood is tough, or maybe I need better jumpers/test wires. I know my plug(the plug on the vehicle side is not 100% intact)
I replaced mine on my 08 tahoe and filter as well, and my oil pressure is still low and my engine light came back on. Idk what to do next.
I fixed it, I traded that sucker in. 😆
Any ideas with this: 09 Z71 5.3 New oil pump and sending unit. 42-45 psi cold start on the gauge. Settles at 40-42 after a minute or 2. After 15-20 minutes oil pressure drops to around 20psi at idle Back up to 40-42 under acceleration. Is this normal on 2nd gen 5.3’s? Mechanic said it’s normal but my previous 00 5.3 and 02 4.8 held 40psi all the time Never dropped
GMC sierra truck lost pressure oil then on led indicator, i was thinking oil filter then replaced new oil filter then on engine tested look low pressure oil and off led indicator, near 20 psi oil gauge
New to your channel but want to say dang fine work! 👍
welcome! And thanks for the positive feedback. Take care

My question for Mr Tim is, is it ok to drive it with a bad oil pressure sensor? I'm 200 miles out in the middle of no where on a rig, will it hurt the engine ? I got a 2010 Yukon Denali with a 6.2. Thank you.
Quick question…what is the expected cost for a shop to perform this task exactly as you did it ?
Had everything done new sending unit new newfilter it was good for 4 miles and an oil pressure dropped started backup oil pressure goes up again you can wrap it up and I'll go to 50 and then it goes to 0 where I should say 2 pounds
also check the Valve Lifter Oil Manifold
I will never use Armor all again
Who is the target audience? A 4yr old
Could not skip the ad
excellent video. my question would be IF this conditions could trigger dtc1815 causing the transmission to fail when shifting as if in limp mode ?? any input greatly appreciated
P.S.what should it be reading for psi on that 5.7 liter. Only code that comes up is the sensor on on bank 2 I believe.
So my oil pressure switch threw the code but my truck doesnt have the gauge. I replaced the switch but i cant tell if i still have the problem. I have a scan tool but it wont show oil pressure. Should my ecu read oil pressure on my 2011 5.3 silverado. Also does anybody k ow if the code would quickly pop up again after i cleared the code?
I didn't replace the screen...wish I would have, got to back and remove the sender all over again. The guage normalizes after a while but the alarm is annoying.
Will it hurt your truck if you don't get it changed
My 05 Tahoe gauge shows 0 oil pressure at idle but running it goes up I have oil in it
hey thx a million for that info...boy was freaking out
Time saving tips are golden, thanks for sharing!
It will save you a couple hours but can't say it's super easy to access but if a fat guy like me can do it you can do it. Hehe
Hey that guy looks like he could be your twin.
I think he is just an imitator.
Imitation is the sincerest form of flattery.
Or was it flactutance?
Anyway just expelling on your comments and I thought I'd add that in passing.
What a relief.
Do you happen to have a part number for the hard plastic hose that goes into the purge canister? Basically just need the clip for that hose.
What if your truck is reading high oil pressure on the gauge
Well done, professional and complete video
thank you.
I just replaced my sensor and screen. Drove a mile down the road and the low oil pressure shut off engine error occurred again. Any thoughts?
Will it still be fine to drive my truck into I can get it fix
I have a 2003 Express van with the 5.3 engine. Oil pressure gauge is pegged at 80 psi all the time, never changes. But now the oil light is coming on when I start it and stays on for 2-3 minutes, then goes out. Does that while gauge reads 80 psi, and does this with engine cold start or hot start.
Probably because the sensor is giving an erroneous reading to the PCM and triggering the message.
@@ThecardoctorTV thank you
