so i've had a cel for little while now, just getting ready to take the car into the shop, and it deisappears. the code was undefined, 0215. i never did anything to try to fix it and last night at around 3:00 i noticed it was gone. so what the hell happened?

 

it's your car telling you that it can take care of itself.

The system resets itself after a certain number of drive cycles. It's completely normal. I'd be surprised if my car filled up the gas tank by itself.

 

Yeah isn't it something like 10 ignition cycles?

 

definitely not. probably more like 50 or 100

 

Err, think I worded that wrong...just...nevermind

 

bleh, congrats on your random ECU code erasing itself.

 

Good Maxima
