02 Altima Idle Problem
 
i need some help with this.. my nissan wouldn't start the other morning so i assumed it was the battery. replaced it and still wouldn't start. towed to the local mechanic to find out whats the problem. they did diagnotics. they said that i had a high build up of carbon so they performed a fuel system cleaning. they also changed to spark plugs because? not sure on that one. well after they did that the car idles up and down in park and neutral. i was told that the car need to reset itself. oh yeah they also tired to install some thing-a-bob to take care of the idling situation but it didn't work. i need help before i take it to nissan.

The idle air volume needs to be relearned.

mpe235 is correct, the idle air volume needs to be reset. The good news is that it is easy to do. I run a fuel system treatment about every 10k, and have had to do this many times. Find yourself a watch with a second hand to make things easier.

-Drive car for 15-20 minutes to get the engine and transmission up to operating temps.
-Park car and turn off key.
-Let sit for at least 15 seconds.
-Turn key to 'On' position, not running.
-Wait 3 seconds.
-Fully depress and release gas pedal 5 times in 5 seconds.
-Wait 7 seconds.
-Fully depress gas pedal to floor and hold down.
-Watch 'Service Engine Soon' (SES) light, it will start to blink after about 7-10 seconds
-Wait until 'SES' light remains on (app. 15-20 seconds after starting to blink)
-Release gas pedal within 3 seconds of 'SES' light staying on.
-Start car, and idle should come down to normal.

It may take you a few attempts to get this right, but don't get discouraged. If the SES light continues blinking and never goes to fully on, drive the car awhile longer and try again.

Good Luck,

B

Hi,
I'm new here and have the same up and down idle problem with my 2002 Altima 2.5 S, manual transmission. I did clean the TB with some carb cleaner.......The SES light is on and after looking other threads about the idle air reset, I've tried many times, maybe 10 times, without being able to make the SES light flash. Used a timer, all.....no result.

Any other instructions because it's a manual transmission? Any idea? I will be at my garage guy tomorrow, not a dealer, to check the codes and do some reset....I just don't want to get ripped........

In the Menu Tab, click on DIY, then click on your vehicle type, then click on Engine Control. There you will find the......

1. Accelerator Pedal Position Learning...
2. Throttle Closed Position Learning.....
3. Idle Air Volume Learning procedures. Be sure to perform all three. Accurate count is key. Get a clock with seconds hand.

The procedures are the same whether A/T or M//T. I did it more than once but less than 5 times. Be patient. Have fun.

triumphtr6quebec 10-06-2011 05:15 AM

I've done all that but no result. I have unplugged my battery for the night to clear the ECU....Will try again.
I will have a code # this pm and report back.
Thanks.
Robert

Medical emergency so all is going to be Friday. Will report back.

triumphtr6quebec 10-06-2011 01:29 PM

Plug back my battery, done the first two tricks with the engine cold and attempt sevral times the idle relearn, no success making the SES blinking.

Will wait for code tomorrow as I'm going the my mechanic at 10:00

Might be something else.....Grrrrr!

triumphtr6quebec 10-07-2011 11:56 AM

Okay,

Up date.....Was at my mechanic's and after looking around, plug the Snap-On scanner and boy........9 codes in there......

He looked for a vacuum leak all around intake, hoses, etc, spraying cleaner everywhere without success and after more than an hour, tried to do the relearn idle. Could not get the SES light to flash for at least 4-5 times.

He unplugged the TB and RPM went down steady at 1200, plug it back.......stopped the engine and the relearn worked.....TA DA !! RPM back to normal at 600-700 but my wallet is lighter of 150$, 40$ for the scan and 1,5 hours.........

I'm frustrated I could not get that _ _ _ _ SES light to blink, I was so close.

Thank you guys for the help.:wavetowel2:

TB = Throttle Body....

I have no idea if it had anything to do with the result or only luck......
