- I am having problems with this car loosing power. cuts off at red light, hard start. CEL-Check engine light code P0171 fuel system lean bank 1. After doing some research, I decided to clean the throttle body to see if this helps.
This is a 2004 Nissan Sentra 1.8L
Once the Throttle body is removed, it must be relearned as to the correcting settings for Accelerated Pedal, Released Position Learn, Throttle Valve Closed Position Learn, Idle Air, Volume Learn.
Procedure
Step 1- warm the engine up to normal operating temp.
Step 2- shut off car wait 10 seconds
Step 3- turn key to "ON" position wait 3 seconds
Step 4- fully press gas pedal 5 times within 5 seconds
Step 5- fully release has pedal wait 7 seconds
Step 6- fully press gas pedal down and hold for 20 seconds engine light should be blinking
Step 7- once engine light turns solid release gas pedal fully within 3 seconds of it turning solid
Step 8- shut off car wait 10 seconds to turn car on
This Procedure applies to the following:
Make/Model/Year/Cylinder/Liters
INFINITI G35 2003 - 2006 V6 3.5L
INFINITI I35 2002 - 2004 V6 3.5L
INFINITI M35 2006 - 2008 V6 3.5L
INFINITI TRUCKS FX35 2003 - 2009 V6 3.5L
NISSAN 350Z 2003 - 2005 V6 3.5L
NISSAN ALTIMA 2002 - 2006 V6 3.5L, L4 2.5L
NISSAN MAXIMA 2002 - 2008 V6 3.5L
NISSAN SENTRA 2002 - 2005 L4 2.5L, 2003 - 2005 L4 1.8L
NISSAN TRUCKS MURANO 2003 - 2009 V6 3.5L
NISSAN TRUCKS QUEST 2004 - 2009 V6 3.5L
Always use a new gasket and check the rubber intake boot for cracks. Replace if necessary.
Use die-electrical grease to keep moisture out of the electrical connections.
Nice video :)

@@diskoeric2248 I don't have the time but thanks for the inspiration.
Very good I learned something good today 😃😊
My 2000 was running rough and I simply unhooked breather hose and put a shop rag under the throttle body and kept saturating it with Berrymans b-12 chemtool throttle body spray cleaner and kept wiping the dirt out as it flushed carbon deposits out, it was hard to start afterwards but it started and has ran great. plus b-12 chemtool injection system cleaner in the Gas ⛽ tank.
Thank you so much you helped me beyond what you think!!!
Use Throttle body Cleaner --Removes varnish better than Carb Cleaner.
Dear. Thanks so much for your video. I have a question. The throtle body have a small screw. Do you know what is the funtion of these screw. I saw that I can move the screw. What adjusting these screw.
Please your help.
My B15 2005 have a problem when a put march the RPM down to 450 Rpm and when I return to parking or neutral the Rpm are in 750 Rpm
I've built cars and worked on tons more, My 02 Sentra has given me the biggest headache I've ever delt with. I cleaned my throttle body and started having high idle so I cleared the codes, did the relearn process, checked for leaks, check MAF, spark plus, and everything just to realize I damaged the Throttle Botty by barely messing with it 🤦🏽♂️
Hey, good video. Quick question though… How do u know if you should change the throttle position sensor or the pedal position sensor. My code reader kind of combines them both into one code so I don’t know which to replace. Any help would be great. Going to get a fuel pressure gauge tomorrow to check that too. Trying to drive this thing until the wheels fall off.
All my codes was pointing to throttle body, last suspect was fuel pump, before you do anything, check fuel pressure at idle and acceleration.
My 2005 Sentra 1.8 has 330,000 miles, runs great, burns 1/2 quart of oil in 5,000 miles and I get 33 mpg :)
I already ran the wheels off many times :)
Do all the b15’s have an electronic throttle body? I have a 2000 Sentra 1.8L. Trying to do a idle relearn on it
@@hhova29 not sure. You need a book.
A little late but I replaced my accelerator pedal / sensor because it was cheaper and easier and it got me out of limp mode and cleared the code.
What do you use to remove the bolts holding the throttle body down ?
Those 4 bolts was removed with an Allan key socket.
Hey I did this and it runs good but idles high and rough any suggestions into idles rough and bounces around 1.5-2000 rpm’s only in park
You need to relearn the programing, check the description of video. sometimes you have to do it 2x.
I don't see a pedal control sensor on a 2000 Sentra does it have one?
Nissan N16 Sunny 2003
I have a problem with RPM - it's completely unstable
The Throttle nail has been moved - and the idle sensor has also been moved
How do I return the Throttle nail to the original factory position?
Hi I am not sure, you might want to google it.
I know I'm late, but I have a 2001 1.8 and if it's been throwing itself in limp mode do I need to hook it up to a computer to clear the code or will it automatically clear?
What is limp mode?
@@BARR8323 Limp mode is a Factory prescribed setting that will force your vehicle...including your Sentra, to NOT run over ??? RPM's to prevent any damage to the Powertrain. The idea is that by limiting the RPM's, you can still drive your car...but only very slowly to get it off the road and to get it repaired---they say..."to a dealer" (which none of us can do with our old Nissans - thus why we fix them ourselves).
Bad news...is lots of problems can cause your car to go into Limp mode, as mine 'appears' to be in now.
I say appears...as I have a P1574 TP Sensors Disagree code, among a few others on misfires also. But that is new one and I think the mis-aligned TP sensors means my 2004 Sentra is Revs/Runs great in PARK..but when I put it in gear I have Zero Throttle response - 750-1000 RPM's. Which is sometimes...like I did at first....mistaken for "Limp Mode". Anyone have this issue with the TP Sensor disagreement let me know.....if u fixed yours. My car is stuck in parking lot now.
My 2002 have no power when accelerating, I replaced the fuel pump, still the same. Could it be the throttle body ?
I have new fuel pump that’s defective. Check the fuel pressure from the pump.
Can you just do the "Relearn Steps without Taking off the Throttle Body and Replacing it?
Yes, I’ve done it a few times to make sure it was not the problem.
Relearn procedure at 9:16 . I don't know why car is STILL sooo having problems . Changed TCB and going to do this .YET AGAIN . Mechanic did the replacing of OEM Hitachi unit . Over a year ago , it wasn't revving up normally even flooring gas pedal . So called " mechanic said it was TCB so he changed it . For allthe good it did .
All the issues I had and parts I replaced was not my problem, the problem was week fuel pump.
@@BARR8323 Sooo why do you think that was ?? Yes it finally left me stranded and both relay and fuel pump was bad . Replaced both and yet problem still continues .. WTH Brand new pump from Rock Auto
Frank Montez when my problems started I dismissed the fuel pump because it was a year old, my wife would drive and all of a sudden it lost power, sluggish at stop lights. Since the pump was approximately a year old never suspected it. Sometimes I get intermittent CEL running lean, I clear the code and look at other parts that could fail. After all the parts I replaced, it circled back to the pump. If you know your coil packs are good, plugs are good, just do process of elimination and don’t dismiss the obvious. You need a certain amount of fuel pressure to keep the engine running, so start by checking fuel pressure.
Some places parts are cheap. There is a reason why, think about it. The throttle body I replaced was OEM hitachi and didn’t fix the problem, lucky I discovered it within 4 days and was able to get a refund.
@@BARR8323 maybe I will check fuel pressure . About a month ago , took it to Nissan dealer and the diagnosis code was for TCB and gas pedal sensor and linkage . And if that doesn' t work for $6-700 then change electrical harness for about that again ..
I cleaned my throttle body without taking it off and my maf. Car wont start now. Ever had this issue?
Cleaning the maf ight have been your problem
I did everything according to the video but still iddle high with the check engine light on. Is any other tips you have. Thank you
I had that problem when I used this special adjective and premium gas, which caused my RPMs to jump up, but eventually, it
Went away.
I have that problem, but I never unplugged the throttle body because if you do it could mess it up and trip it or something
Hi any one can let me the ubicación of the TCM Sentra 2000 ?thanks
I have an 03 spec v and it has code p1102 and p0420 i changed the 02 sensor , fuel pump, spark plugs and ignition coils i also cleaned the maf and the throttle body but it wont start unless i pump the gas and after i start driving it doesnt stall but it revs at 2krpm and on every gear it wont let me pass a certain speed on 6th gear i cant pass 60mph any help ?
Check your fuel pressure
@@BARR8323 will do ! thanks for the reply and i will update soon
While P0420 does not pose a danger to the driver, it can cause driveability concerns such as a lack of power or poor acceleration if left unrepaired. It can also cause severe damage to other components of your vehicle if not addressed in a timely manner. P0420 typically means that a converter has worn out or degraded-not obstructed or clogged. But if the case is the latter, it can lead to engine performance problems, such as a lack of power, rough idling, and stalling, which are some of the common signs of a clogged catalytic converter. When the voltage coming from the Mass Air Flow (MAF) sensor to the Powertrain Control Module (PCM) is low but within range, a P1102 trouble code is stored. This is what I found online.
why does my 2000 sentra gxe start idle jumps up and down cant give it gas then motor dies
Any Codes?
MAF sensor
Damages throttle position sensor
Not for electronically control models?
I have a 00 Sentra gxe and recently been getting the codes p1130 and now p1165. Hardly use the car but warm it up and drive it around the block once a week. The dealer told me it was the swirl valve and that is built into the throttle body.
Can any throttle body replacement fix this issue??
I had the same problem it's not built into the throttle body
You said the throttle body was not the problem would you tell us what the problem was you discovered please?
Crankshaft sensor in the bottom side, it happen to my sentra
Fuel Pump.
Yeah left me stranded and checked on gas coming in at the line at engine compartment and nothing . Checked fuse and relay and relay was bad . Replaced relay and still no gas when I cranked it . Replaced fuel pump and less than a week still doing the same . It's rough idling and when I press gas pedal doesn't rev up .. WTH
Hook up a fuel pressure gauge in the fuel line under the hood and check the pressure, I am suspecting you’re having an intermittent fuel pump problem.
@@BARR8323 never done that type of thing before. Where do I rent / buy or possibly borrow this gauge?
Harbor Freight have a kit, look for the fuel line coming up under the hood from the pump, disconnect it and the gauge goes in line. The pressure be approximately 50psi. If your pressure is not there start checking what you checked before. The only reason I say Pump is I went through a few pumps and the last on had me baffled because it was 6 months old and I thought it was something else so I did sensors and throttle body, nothing worked so once I connect the gauge and rev the car let it warmed up noticed pressure was off, swapped the pump out I went a little more expensive and worked good.
@@BARR8323 OK but did you read my comments about me taking it to the dealership and they said it's either TCB, pedal sensor, linkage.. Or if that didn't work, replace electric harness? Do you have any idea if they check fuel system? I still have the paperwork on this $85 " diagnostic"..
What was the code? Sounds like they are guessing. I can only comment on my experience.
Couldn't you have used Sea Foam?
I cleaned my trottle body and now I can't accelerate. It drives slow. Please help
Did you do a relearn?
@@BARR8323 no I did not. I just now googled how to. Thank youuu so so much! I bet this is the problem.
Super! I see you have the relearn steps. I just screenshotted it. Thanks
czcams.com/video/zbY5zyW_-Zk/video.html
is the relearn the same for sentra 2.5L ?
That I am not sure of, you can try it and post back
It is a QR25, the relearn process is the same.
I think throttle body on 02 Sentra I have is really dirty never been cleaned dirty
You should let ppl to learn how to relearn the throttle body before doing this, cus they will have another problem, you didn't mention that
what other problems please. thanks
Are you saying that an alternative to replacement is just to relearn the existing throttle body to correct issues??
@@nevmitch2 yes it's called the pedal dance.
It involves turning the key to accessory and pressing the gas pedal a certain number of times, releasing the pedal and then doing it again. A quick Google search for Nissan pedal dance should help you out
The procedure for the pedal dance is in the description of this video actually !
Just a heads up these throttle bodies are VERY fragile! I took mine off to clean it and put it back together and started having issues. Tried to swap it with a used one from a parts yard and broke that one too after being even more delicate. Had to take it to a shop and cost me $600. I would NOT recommend doing this cleaning unless you are very skilled.
Says....the Nissan Shop Supervisor who makes his living off robbing us. It's METAL....it is NOT FRAGILE!
