2002 V6 Camry won’t idle after battery change\cleaning of terminals

JimReno

Hello everybody,

I changed the battery in my 2002 Camry (V6 Auto Transmission) two years
ago at 40K. I remember after I did that the car would not idle. I figured
it just needed to re-learn my driving patterns ECT. Seems like it did and
every thing has been fine. Last weekend while tuning up the beast I
noticed some corrosion starting again on the terminals so I removed and
cleaned them (Negative wire first). Now the beast won’t idle again. I have
removed and re connected the terminals a few times and have driven over 500
miles and it still won’t idle. Any ideas on how to reset the
engine-control\computer memory that adjusts the idle air by-pass. Or
something along those lines. Chilton’s does not have a manual out for the
2002 Camry yet. Current mileage 82K Any help on this would be greatly
appreciated. Thank you in advance. Jimmy

I would look for a loose wire/broken connection somewhere close to the
terminals, esp the + terminal.

I don't think that this would solve your problem but here's how you
reset the ECU: pull the fuses for it. In some cases, there are two so
you'd obviously have to pull them both for about 1 minute.
