You didnt show how to clear a permanent code. You just explained what needs to be done before the PCM itself erases the code, not you. No help.
You cannot erase a permanent code in 2010 and newer vehicles. Only the ECU can get rid of it by detecting that the problem has been fixed. Now how long it takes to do that? No one seems to know the answer to that. Point is really you can ignore permanent codes. They are not hurting anyone being in there as long as your check engine light is off.
@stevew9563 bull. Emission test will not pass even if pending or confirmed codes are not active
@@BernieJr89unless you drive a diesel
@@stevew9563 can you tell that to the state of california and its smog check system please
A Note for CA owners who may come across your video when they are trying to pass a SMOG check. You do not have to clear a Permanent code in order to pass a smog check. All you have to do is drive at least 200 miles and do at least 15 warm up cycles (Different from drive cycles) Then the SMOG machine will ignore any permanent codes you have in there.
Other than getting a smog check there is no need to worry about a Permanent Code in your car. Nothing is broke and there is nothing more to fix. Don't throw any more parts at it!.
@@mg8718 Correct needs to see at least 200 miles since the codes were cleared. Go 201 just to be safe!!
What you mean nothing broke @Steve W
@@sachskailg2784 - That's a hard concept to get because we are so used to codes meaning something is broken. But If your car is 2010 and newer and all you have is a permanent code with no check engine light nothing is broken. If you drive it to get the monitors ready and you get a check engine light then look at the new current code that came up and repair that, but ignore the permanent code.
I have a 2012 Toyota thundra didn't pass smog because of a pending code PO4056 that's the same cycle told me to do but still hasn't cleared
@@2010nvillanueva - Do you have a Pending code or a Permanent code? Do you have a check engine light on?
Thanks for info. Awesome video and explanation.
Drive cycles.. lol who knew.. I wish the launch scan tool had an explanation about that, but, who needs them when I found your video..
I have a permanent code for my DPF. I got a replacement one cleaned and tested but still have the permanent code..
I had 3 litres of engine go through it after the exhaust side of my turbo collapsed in on itself so cleaning wasn't an option.
I look forward to doing some drive cycles to get my 4wd out of limp mode
THANK YOU! I didn't know what INC meant on my scan tool. Now I know. I'm hoping mine will clear after a long trip. (O2 sensor bank 1 sensor 2 voltage high appeared after running through car wash with underbody blast. Hoping it was just moisture in the connector.)
Thank you - it was a little rushed but I just played it again - drive cycles is not common knowledge at least for me. The smog check tech won't offer the simple just drive it for a while thing that a mechanic does - it's frustrating and ends up costing $$$ while I think something is badly wrong with the car. It is kinda sleazy especially in California that the cars computer does these test / drive cycles which have specific range of aspects that must be met in order to pass a smog check... meaning that you will get charged for a test that isn't what a smog check use to be but something a scanner will provide as far as if it's a pass or not - before going for the test so you just know it will pass... otherwise it's pay again and again for the problem... it's actually crazy!
I kept waiting for you to explain what a drive cycle is.
A drive cycle is just a certain way to drive your vehicle that enables it to run it's tests. It's slightly different for every vehicle but most of the time just standard street and freeway driving is enough to perform the tests. Some cars you have to get really specific and try to do it exactly as the drive cycle wants. So really just depends on the car you have.
I had a permanent code for 02 season after I replaced it i did exactly what you showed in this video and it disappeared so thank you and yes driver it ,stop it, open the door for 50 seconds and drive it again do that for a couple time and will solve the problem thank you again i had my my emotions test passed already
Be sure to look up the prescribed drive cycle for your car. They’re usually very specific but the benefit is you aren’t randomly driving and guessing if you’ve done / driven enough. This is the fastest route to clearing the permanent codes after your repair.
Dudes. Got Covid.
Awesome tutorial , very detailed instructions
I got a foxwell elite with bmw software for a 2003, but it is still the same basic stuff. There really aren’t many other options than any other five dollar ELM OBD…. Now I regret spending over $100 on it, six months after purchasing, they will not even support or update, maybe it’s just me but that won’t cut it
You sure you should be able to get into all the BMW modules more than just Standard OBD. Does one of your icons on the front page say OEM OR BMW?
Video starts at 4:10 youre welcome
As what @JaboTheMechanic have said in the video. Sometime even if you have fixed everything. You gitta have the computer RE-programmed because the permanent code woudn’t erase. He said that maybe you need to update the TSB (technical service bulletin) for a program update.
The only way to clear permanent coach is disconnect the battery for 20 minutes. Or do enough drive cycles either way you got to do the drive cycles to pass emissions
Will disconnecting the battery for overnight erase a permanent code?
No. They stay in a part of the memory that does not get erased that way.
2016 mustang GT......40 drive cycles after fixing random misfires caused by IMRC.....This is a major headache for people who don't understand how ECU and PCM work......The quickest way other then drive cycles is to flash the computer and load new program.....
Some tuners have reported even after a reflash the PDTC is still there. Sits in a part of the memory that does not get writin over during a retune.
So, turn on keys, open door, take keys out, close door and turn keys on again will clear permanent codes?
No, the car needs to cool down to 120f and heat to 180f in order to complete a driving cycle
Excellent explanation! Great job seriously !
Good morning
I have my Opel Insignia B which is similar to Buick Regal, I have U1520-00 code and I tried to clear it but it won't be cleared. As far as I know it's related to power sounder of theft deterrent system which is actually not sounding, can you please help me to restore everything back to normal?
Best Regards
I’m months away from being exempt but have to get emissions one last time for renewal. Small evap leak not fuel cap not purge valve… it seems like it was only when you fill the tank completely, but now it’s showing check gas cap off and on and eventually check engine light. I really would like to fix it but if it’s prohibitively expensive…
Done a smoke test on the EVAP system?
I got a 2013 camry p0302 misfire changed spark nd coil nd injector the chek engine pnly turns on at high way speeds sometimes with the traction controls car symbol but it only says misfire and spark plugs not oily wet what can it be
I’m got a p0303 right now and haven’t solved the issues what did you end up doing?
Interesting what you said about the permanent codes on the newer years. I just ran into this yesterday and i have an innova computer that couldn't erase it. This is the first time I've ever had that problem as it's always deleted bad codes till now.
So i think I've cured the problem and i take it i need to drive it to erase it....
My issue appears for now to be generated from a dead battery i was unaware of after attempting a remote start from inside the house 3 times not knowing the battery had died. This dropped it to 8 volts and i believe this caused a TCM code to pop up. At least i pray that's all that happened.
2019 Chrysler 300. I haven't driven it yet, i hope this is correct as I'm worried how it's going to handle shift points when i get on the road with another battery.
But hey, others say you can short the battery cables for several hours and remove these type codes any thoughts on that?
Thanks for your insight!
No do not short cables on any car that has computers in it.
What do you do when the car doesn't start to do drive cycles
Can you use it if you can't start the car
You don't seem to have a whole lot of knowledge about what you're talking
I got stored code P0171 on 2006 Honda Civic si 2.0 coupe everything is fixed what can I do to fixed this issue I have no vacuum leak,thank you ahead keep on your helpful videos🙏
Is your check engine light on? And what do you mean by a "Stored" code? Does it say Pending or Current?
omg i have this right know it is the worst!!!!!!!
i replaced my MAS and i think it worked but i think a have a problem with a link to my charcoal canister? im going to make a homemade smoke machine to find vacuum leak. this help me to understand a lot (The Trainer #70 - EVAP Testing Tips)
Hello there i have a question
So i have sonata hybrid 2016 limited and there were a permanent code for p1235 obd 2 and i few drive cycles and now the code is pending ...
What should i do to clear it so i can pass smog in California?
Think you will have to make a repair if the code is Pending. That means if the problem happens again it is going to turn on the check engine light. Here is a vid on that code: czcams.com/video/mSRPZinuBLU/video.html
I have a pending code. I fix tge issue and im readiness is all good. Pass smog but still have that pending
Do you know if VW trouble codes are recorded by the vehicle ?
What you mean recorded? There is an OBD standard to a codes.
Thanks man you a big help ty..
I’m trying to sell this car to a dealer and this 2012 Nissan leaf has two warning yellow and red⚠️ signs on I need them off I have obd2 scanner veepeak
I had a misfire in cylinder 5 change wires, coil and plugs cleared the codes but it still showed misfire in 5 found out the plug was a little longer than the rest of the plugs and the tip would bend in so there was no gap so I cleaned up the one of the old plugs and it worked no misfire now I've been driving for a over a week now it shows misfire on 5 again but my minivan is running fine I think my computer is showing ghost codes
Thanks for your video I did subscribe
I have a cylinder 2 misfire which is a pending code and not a stored code, Or permanent code.
Replaced spark plugs which have been installed for about 24hrs now from my comment and pending code is still there.
Is there a way to clear pending codes on the foxwell nt301 or does it clear after a certain amount of drive cycle?
Sure a pending code you can clear at any time.. If you made a repair it would be smart to clear it all out and see what comes back up , if anything.
I have mass air flow sensor code. Do i delete the code then switch to new sensor or do i switch to new sensor then delete code?
Swap new part than clear codes
Please help my codes on bimmer link error no present but stored and I have a check engine light on .
Before a mi have a vacuum leak and error was present .
Please need help I have bimmer link to reading codes .
Thanks
what about anti lock sensors and brake codes?
Those usually do not turn on the check engine light as they are not emissions related.
How can i clear a pending P26c8 code on my 2018 buick lacrosse?
Sure but if you do not fix the problem that caused the code then it will just come back.
I just need to clear it to pass inspection
Well in most states they check to see if the monitors are set. So the pending code will probably come back in the time and miles it will take you to get the monitors set. But try it , might get lucky
Can the dealer clear a permanent code w/o completing the necessary drive cycles?
No.
Thanks so much big dog
You could earn 100000 subscribers if you could figure out how to reset the service. Light for service oil. That's days on permanently after your car approaches 200000 miles. BMW with an N52 motor.
My 13 Infiniti g37 was over heating caused a the fan fuse was blown I change sb it it’s not over heating no nomore , the code p01217 says it’s over heating is a permanent code that pops up can’t pass smog , so I drive 15 cycles and still there can’t seem to get rid of the code pls help ??
You drive 200 miles and 15 warm up cycles and the smog computer will ignore the code. It wont clear it but it will be ignored. Thats 200 miles and 15 warm ps since you cleared teh code after the repair. Don't clear codes anymore as it resets that count.
@@stevew9563 wow thank my Steve I will go get my smog test then
@@AlvaroFG2 - Make sure your monitors are ready as well.
So I have a permanent code p0087 “ Car runs fine can u guide me what is the issue
If your check engine light is off there is no issue. A permanent code with no check engine light does not mean anything is wrong with your car.
I have permanent TCM code P0882 and my scanner will not erase it. What scanner can u use to clear it?
No scanner can erase it. Do you have to pass an emissions test in your state? What state?
@@stevew9563 Im in NC, however the light shows up in my scanner but it doesn’t pop up on my dash,. Do I need a OBD scanner for transmissions?
@@manuelsalgado8510 - Do you have an emissions test to pass? OTherwise just ignore it.
No, no scanner can clear it.
This is a really bad system the companies brought on this vehicle. They gonna expose ppl to go back and forth to a mechanic that they didn't even know he fixed the problem or not, until they found out after those cycles. Which is terrible!!
Good mechanics are supposed to verify thier fix by completing the associated drive cycle and make sure the code that it came in for does not come back up. THis is of course time consuming and many mechanics just send it and hope they fixed it.
@stevew9563 you are right, that's how it has to be done. my wife car is facing a problem that the mechanic didn't even do the cycle to check his work or explain it for her that, and he made us returned so many times.
A waste of time I can never get back.
Didn't show
To much jabber confusion. Get to it or stop.
Permanent DTC's are special codes used so you can't fake a passing emissions test. They don't want you clearing all your DTC's right before you pull in to get the car inspected. With normal DTC's that are not hard faults, you clear the codes and wait for them to come back. Permanent codes are the opposite. You clear the codes and wait for them to go away. They give the PCM enough time to determine if the problem was really fixed, or if you just did a reset. People sometimes get confused because permanent DTC's are not really permanent.
@@AT-wl9yq - Yea Permanent is a bad name for them. Wish they came up with something else. The "We gonna hang around a while to make sure you fixed your junk" codes.
Got a permanent codes for P0420, P0455 & P0441.
Fixed everything from sensor, gas cap, pcv valve, purge valve & canister.
Mine goes from STORED, PENDING to now its PERMANENT. Drove it around for cleared the codes and drove it around for 20-50 miles then the codes would re-appear back again.
So i cleared it again then same issue. After 20-50 miles. All 3 codes would pop up again.
So how can i fix this? As soon as it would pop up just continue driving it for 200 miles and see how it goes?
NOTE: as soon as i replaced the parts mentioned above. The car is smoothe to drive already. Got no issue except for the codes.
Any help @Jabo the mechanic

If you tune a code out with hp tuner will the perm code eventually go away? p0449
Would have to ask HP tuners on that. If HP tuners strategy to eliminate that code is to not allow the monitor for that code to run then yea it may never clear. Fora PDTC to clear it wants to see the same conditions present when the code set 3-40 times with no error. Or it wants to see the Drive cycle conditions met for that monitored system 3-40 times with no error. If HP tuners gets in the way of that then yea it will be there forever. Do you have to pass an emission test? What state?
Dude you went thru that in seconds…. Clicking and scrolling? Slow down a few seconds and stop talking 100 miles an hour….. I had to get a notepad and rewind every 2 seconds….
CONFUSING AS HELL....YOU DIDN'T EXPLAIN DRIVE CYCLE..as though everyone knows
yea it is , u have to drive like ten times after clearing codes ,
This is how to scam the buyers.
This dude talks alot
That information is wrong. A driving cycle means that the car cooled down to at least 120f and warmed up to at least 170f. Other than that it won't count as a driving cycle, at least on Toyotas 2010+. You could manage to have a water hose blasting cool water on your plugged temperature sensor(no need to remove from the car) to trick the computer that driving cycle happened 😊
What you describe is commonly called a "Warm Up Cycle" a "Drive cycle" is something different. A drive Cycle is a specific way to drive a car to complete the monitor tests. It may actually perform a Warm up cycle while you are doing a drive cycle but generally a warm up cycle does not need any specific driving pattern, in fact you can do it just idling in your driveway.
