Note: This method of relearning the idle on Nissans only works on 2002 thru 2011 year vehicles.

You need to do a relearn of the Idle on your Nissan if you are experiencing idle surges between 800 to 1000 and 1800 to 2000 RPM and/or have a P0507 error code.

There are many videos talking about how to do the idle re-learn on Nissan cars, but none explain that the check engine light should flash slowly then quickly if the re-learn steps are done correctly. This video first shows you what happens when a re-learn fails, then it shows you what to look for if a re-learn is initiated correctly. I hope this helps everybody save $100+ by doing it yourself rather than paying a Nissan dealership. BTW, I cleaned the throttle body as a step to try and fix this problem; I did not have the key on or the battery disconnected when I shoved a screwdriver in to hold the valve open, and some say that will damage the TB. Do not assume that cleaning the TB will damage it; it didn't in my case.

Before doing the re-learn, you need to do the following:

1) Confirm battery is good (voltage 12.9V or higher at idle).
2) Drive the car for 15 minutes to warm up both the engine and transmission. (It may be adequate to just idle the engine till fully warm)
3) Turn off as many electrical items in car as possible. Make sure
lights are off and doors are shut (dome lights not on). You do not have to unplug the radio like some suggest; basically if your battery is good, the electrical items being on is not critical.
4) Center your steering wheel.

The following are comments posted by a visitor to this video; he described how he was able to relearn the idle on a push-start (no key) Nissan...

So I just did this on my 2009 Nissan Altima and it worked after a few minutes of trying. My car has a push start so it’s a lil different but the same concept. First off make sure the car is warmed up. Next turn car off and wait 10 seconds. Double push the button to the on position ( don’t have your foot on the break pedal) and as soon as you first push the button, start counting 1 Mississippi, 2 Mississippi, 3 Mississippi. Next press down on the gas pedal 5 time, hard then right after that count out 10 seconds and press down on the gas pedal. It will take a few seconds before the check engine light starts to blink. Make sure your other foot is ready to press on the break pedal so you can start the car when the check engine light turns off. It was a little tricky but after a few tries and following this amazing video, I finally got it to work! My car runs a lot better! If anyone has question pertaining to the push start method leave me a comment and I will get back to you.

Was your push too start Nissan, was it in Idle Mode (Limp Mode)?

Tim DesJardins
Destiney Guzman so my car was in limp mode, so I disconnected the battery for 24 hours. Next I performed the steps above and now my car is running good. I noticed that the battery should be disconnected for 24 hours before performing the procedure.
