You guys save people money that don't have it. Taking a car to the dealer is very expensive. They charge 100 dollars just to put it on a scanner. Thanks a lot for helping people .
Hi Falcon. I Can not Thank You Enough!!!!!!! I have 2007 nissan sentra 2.0 engine car ran terrible i cleaned the throttle body and the hose to it was cracked i replaced it. After cleaning throttle body ran better but the idle was high and surging while driving . Well thanks to You i Followed your Procedure it worked on the First try i am totally Amazed my car runs PERFECTLY !!!!!! . Again Thank You!!!!....... Frank
I tried this method on an 07 Altima several times, did not work. I finally hooked up my ThinkDiag in hopes that it would have the ability to do the relearn, and it did. Fixed it perfectly. We appreciate videos like this, thank you.
If this isn't working for you and you still have a high idle and check engine light, do all 3 procedures with the engine fully cold! It worked on my 06 Nissan Pathfinder. I cleaned my TB and my truck started idling around 1K and check engine light. Tried this procedure about 20 times with engine and transmission fully warm and it did not work. Next day, I thought I would try it with engine fully cold with nothing to lose and BAM, 625 RPM after a few minutes of warming up. Good luck!
Worked great on my Nissan350Z! Thanks a lot bro! Worked on the first try too! After I had my CamSensor Bank replaced, my car was idling around 1500 rpm! Now I’m down to a solid 500rpm!
And just a follow up, anyone doing this: after it works and your car is idling in the right zone, leave your car running for about 10 minutes, at least. Turn on your AC and your rpms will go up again. Let it run for about 10 minutes again.
Thanks, it worked great!. I did clean my throttle body and my RPM increased. I thought that was normal till I got that P code. You video helped me work that out.
Same here for my 2006 Sentra SE. went through the procedure and was going to redo it so I started the car after noticing if din’t flash within 20 seconds, but when I started the vehicle the engine light was off and idle was back to normal
Dude omg....tried this last night like 40 times with another dudes video, could not fucking get it... Literally 1 try with your video, SUCCESS!!! Thank you my brother, you really really helped me out today!!!
Dang, I literally saw the rpms drop to normal level, within spec. So I test drove it and it SES might came on and now its back to high rpm, not as bad as before, but 1100 rpm in park at idle. What do I do my man??
Have you checked vacuum leaks or if the throttle body is dirty? Also all Nissan are known for the intake hose to crack with time. The one between the MAF and Throttle body.
This one worked for me, 04 altima, after trying multiple versions found on RU-vid and the forums, including those claiming to be "from the factory". This one was found by my beautiful, voluptuous, curvy, sexy wife, so credit goes to her for finding this video.
I have 2006 Nissan Altima and just bought it used (it is July 2018). I bought it off my nephew's used car lot - they just got it as a trade in. My symptoms are: I usually get steady idle at 1000 rpms in Park or Neutral. Occasionally, I get steady idle at 1500rpms. But abt every 8th engine startup it'll immediately dip once to abt 600rpm and steadily climbs to 2000rpms where it will start a cycle of dropping & surging between 1000 and 2000rpms. It stops the surging & high idle as soon as i put it into gear (drive or reverse). It will not do it on next few cranks. It'll take about 6 or 8 cranks to hit it again. My MIL is P0507. The dealership changed an engine mount the day before it started happening. At first my nephew thought the mechanic might've left something unhooked or knocked something loose pulling off the cover to get to the engine. Is this a potential? What all should i check? Do you have a video that covers every point of failure in this system? Thanks
have you checked for vacuum leaks or your spark plugs? i dont think there is anything around the motor mounts that could be disconnected to replace them that would cause this issue..specially sense it docent do it all the time, Have you checked if the throttle body is dirty too?
Falcon's Garage i checked an electrical connector that plugs in at the air filter box. I opened the air filter box to be sure that the filter was clean. It's not new, but it's not bad. I have not looked at the throttle body or any of the vacuum hoses. Do you have a video that explains how to check vacuum hoses, Air valve, IAC, throttle body.... and changing spark plugs on nissan. (Ive changed plugs on 1973 Honda Accord cvcc. But ive never done a tune up on car with fuel injectors. ) I partly disabled am able to do some repairs myself. I was an aircraft electronics technician in USAF. i have an electronic/electrical'mechanical education. I have a little experience on cars (belts hoses, alternator, battery, solenoids, wiper motor, headlight switch & wiring, choke, ... nothing major. Anything using hand tools I can often do as long as i have instructions (how to with dos and donts). Any help is appreciated.
Thank you. I will watch and like. The day after you replied, the CEL went out on its own ... about 3 driving cycles after I had reseating the (MAP ?) connector at the air filter box. Is this a coincidence? Also I have not had the gas cap open to refuel, in case the gas cap was the problem (I tried to get the cap as tight as possible last time I refueled). For now, whenever I start the car, I immediately put it into gear to avoid idling in park. And whenever I park the car, I immediately shut off the engine to avoid idling in park. I am doing this to avoid any re-encounter with idle surging to keep the CEL from coming back on. I plan to change the gas cap the next time I refuel. I had already bought it from the Nissan dealer (before the 507 CEL incident) because I was dinged on the state inspection for not having the factory specified gas cap. They didnt ding me on the CEL but it might be a problem for the emissions check. I am trying to solve it before I have to take it in for emissions check.
I did it with you perfect the check engine blinked then went solid and I cranked it and the thing I notice is it idles at 1 but if I tap the pedal it kinda jumps a little bit prob half rpm and then settles. Feels unnatural. Did I do it wrong maybe?
A lot of people here are talking about when they cleaned their throttle. I thought only when you disconnect the IAC Valve electrical connection, you need to do the reset. Am I getting confused here? So you need to do this even when you clean the throttle head? I am not removing any electrical wires to throw off the computer setting. I had mine sprayed and cleaned when I found a crack in the intake valve hose and removing the hose only. I appreciate your response. Thx
Wait lol I did again and this time the rev settled at 500 and didn’t seem to be jumping anymore....Bro! You are the shizzznit my friend lol thanks so much! Liked subed 👍🏼
Ma Nissan Murano 3.5 V6 2006 AT essence ne démarre plus. C'était dans un embouteillage, le moteur avait coupé et j'ai essayé de démarrer mais en vain. Que dois-je faire ?
07 maxima: I wasn't doing it right at 1st but finally got it. When it started the light went off but came back on. RPM definitely went down & seems stable but what do I do now??
Ok I have a 2006 nissan maxima 3.5 its putting out code p0507 I tried your video step by step with you and the check engine light never blinked can there be anything else I need to do?
I did a tune up and cleaned the throttle butterfly with battery connected and got the code too. I tried doing the relearn on a friends expensive scan tool that said it does it, but p0507 came back. Now if i try this procedure ('service engine soon' already on). should i clear the dtc first then do the relearn or leave dtc stored with light on and do relearn....OR does it not matter. Thanks!
hey man I just saw your video and great explanation but I had a question I have a 2007 Nissan Frontier 4.0 and I ended up cleaning the throttle body and the same code popped up. I do feel like the truck is pushing itself a little bit did your car do the same? and do you know how long it takes for the chemicals to go through the engine because the shop told me that it takes about 50 to 75 miles for it to get it through the system
I used throttle body cleaner. i actually had to run the test twice and now its running better than ever! thank you! very good explanation. i just get scared when things are not working on my truck.
I had the throttle body cleaned on my '07 Nissan Versa and now the RPM's are jumping from 1-2. Do you know if this procedure will work? I don't want to spend the money on a new throttle body if I don't have to.
Thanks! my 2015 Rogue just quit yesterday. Turned out Pos cable was loose. When it came back to life after a jump, idle became radical and car was jerking and struggling, like fuel pump. I am starting with the IAC. If I clean throttle body, can I try your procedure next? Also, do you recommend a code app for iPhone or some other not-too-expensive checker? thanks again!
I have a 02 Infiniti Qx4 it doesn't want to start when the engine is cold without pressing the accelerator some just enough to bring it to 5-600 rpm.. After giving it gas for just few seconds it runs fine at normal rpm. After engine is warm the car will start all day long.. Everytime I search this is what comes up.. Any thoughts.. Is it my TBS?
Thank you for the video Falcon's Garage. I have a 2002 Nissan Altima 3.5 SE. It's pulling this code P0507. The shop where I took it, is telling me that I need to replace the Idle Air Control Valve. But I previously replaced the throttle body with a new one and I don't think it was relearned. I wonder if that's what throwing the code. Any suggestions. Thanks!
Had code P0171 (system too lean bank 1) so I decided to clean the MAF sensor and throttle bottle with the appropriate cleaner (I’ve don’t it before). Resulted in added code P0302 (cylinder 2 misfire) and it revs up and down constantly. Filled it with Techron complete fuel system cleaner and filled the tank. The previous codes then disappeared and I now have the constant reving plus code P0507 idle control system RPM higher than expected. Should I replace it?
P1122 and P1126, eratic idling, CEL and VDC Off...? Replaced throttle body and relearned virtually everything and cleared codes, still get P1122 and P1126 on startup. Starts up perfect and then the lights come on and the idle goes either low constant or all over the place between 750-1650. Any ideas?
Falcon's Garage Thinking it's the throttle control relay. If that fails, it throws both codes. When I start it up, I can hear a crackling noise in the area where that relay is located. I'm guessing that if the relay fails, it can't communicate with the throttle body, and thus the codes for both the circuitry and the throttle body itself will display. Does that sound about right or am I way far off?
Shannon Wetnight that sound could also be the replay engaging. When ever the engine is off but the cars ignition on you should be able to press the gas pedal and the throttle body should engage check that it does also. Also see call the dealer and see if there is a computer update on your car. Sometimes they develop glitches on the computer and an update fixes it.
Good video, we had to replace a starter on a Nissan Armada and I noticed the next day the idle was out of whack and it even accelerated slowly on its own and shifts gears , could this procedure of changing the starter and putting things back together have anything to do with this issue ? Thank you kindly
So I get the same code but mine after I drive it like 30 minutes it starts jerking and after 20 minutes of it starting to jerk it wont accelerate unless I turn it off and let it cool for a few minutes does it sound like a icv is bad ? I changed the throttle body
Falcon's Garage well I was told it's for sure the idle air control valve and it costs like 900$ I've replaced the alternator, battery,and the catalyst converter do you think the Iacv would cause the truck to stall like that ? Only when warmed up completely
hey I have a Nissan sentra 2007 I clean my throttle and a check engine light turn on. now I get a p507 when on idle is on 1800-2000rpm I try reseting it but it wont work
After I removed and cleaned my throttle body on my 07 Armada, the check engine light came on and now it won't turn on. Well, it turns on, and dies. I even hit the gas when it turns on and still turns off. Please help.
Mine poppee up on my gfs car because I took the sensor plug off to check her ail filter and forgot to plug it in when she started her car.. Gotta try this out.
I have a 2004 Nissan Altima and I tried this procedure like 10 times and I can't get me engine light to blink. I've done it at the same time as I watched the video also. I cleaned the throttle body. What am I doing wrong?
I know is a bit late, but did you find out what the problem was, im having the same problem, my check engine light wont blink during the relearn, I'll appreciate it if you can help me out.
it must've tripped the starter in the process. because I just banged it a little and everything is fine now. just something to know just in case it happens to someone else. thank you
Any fixes ? Did a engine swap in 05 Nissan Atimla 2.5LS. New throttle , RPMs bouncing from 1100rpms to 1900rpms. Wont response to r Any learning procedures. Any tips ?
i have 2002 nissan maxima 3.5 and i have code 1122 i bought a new throttle body and gas pedal as well i have tryed to do that relearn procedure nothing at all my RPMs are way too low I press the gas and it only goes to 1 1/2 rpm sometimes 2the most i ran out of ideas hot you can help thanks
i already did and it looked like crack so what i did i got another one from another car and i did the wiring and it was working fine for like 3 months and then one day i turned it on and its been like that since
Might be the same issue again... maybe...... but also check the rest of the wiring not just the connector. does it do this all the time or just periodically?
The relearn should work with out having to clear the codes. But you will still have to clear the codes after the relearn. So aither way it needs to be done. If you don't. It will eventually do it it self but it will take a couple of engine cycles.
I just went to check it and the check engine light disappeared. This is the second time this has happend. Could it be a more serious problem? But all is good for now. Thanks for your help!
HI there. I have the same year murano. removed the intake manifold for maintenance, have the same code, I did same steps u did . my check engine never blinks, the idle it did drop to 800 or so. but still it's high idle while coming to stop completely, do I'm doing something wrong Or I have to repeat the steps more then few times. have repeated the steps 3 times, engine light never blinks while doing the rest learn ? any help ? thanks
183guti sounds like your doing the correct steps. Double check that you don't have a vacuum leaked somewhere. Like the throttle body boot or something like that.
yeah the rubber hose that goes between the Mass Air Flow sensor and the throttle body, i've seen that sometimes when it gets put back on it sends on the mouth of it,
