Reseting the ECU on a 2k2 MAX
I'm just wondering for future reference how you reset the ECU on a 2k2 maxima. I'm gonna be doing some mods and such and i want to know how to reset it. and before someone says it, the leave the negative battery cable off trick DOES NOT WORK.

try leaving it disconnected overnight. that's what I did and it took care of it. If it doesn't work ... then it makes sense that whatever set it off the first time is still present and needs to be corrected. Unless they have done something different in the 2K2 models that trick should work. And like I said before ... if it doesn't that means that whatever set it off needs to be corrected ... meaning a more serious problem.
PCGuRu2K light came on and after disconnecting the battery it came back. He found out that and O2 sensor was bad on the front bank. Well you don't really want your ecu to disregard that do you!

According to the manual for the 4th gens it takes 24 hours to reset the CEL light. I did this for my 5th gen and it worked. I let it sit for 24 hours, I don't know if you could get away with less.

After 24 hours the ecu is reset, no fault codes. If you have a continuing problem, the codes will reappear.

Resetting the ECU can be done by removing the negative battery cable. On ANY car. The only problem is you have to leave it off for about 15 minutes. The PCM <----what its really called has memory, and the only quick way to clear the memory is to actually press and hold the brake pedal to clear it out. You only have to hold the brake pedal for about 30 sec.
