is it possible to reset my CEL codes myself? because i heard that disconnecting the battery wont clear them. just postpone them.

 

Buy a code reader from your local auto parts store, then you can read the codes and clear them after the problem is FIXED.

 

no money haha im broke and jobless (searching though)

 

Disconnecting the negative terminal from the battery should clear the code. However, if the issue isn't fixed, the CEL will come back on, since there is still a problem.

 

the only way to clear them is to disconnect the power leads and hold them to negative for 30 seconds to a minute. The only problem in doing so is you also reset the computer so for the next 50 starts it is re learning your driving style....


or take it down to AZ and have them read the codes and you can clear it on their reader

 

AZ won't let you clear codes with their reader, they said it's because of a lawsuit. However, you can buy, or "rent" as they call it, one of their readers, and return it when you're done.

 

mine just hands the reader over to me and says that I cant do it, but you can

 

He has obdII. I thought it could ONLY be done by a scanner?

 

i have an obdII and i use the positive to negative method before. works just fine but again the down side is your computer has to relearn which can be a good or a bad thing depending on how you drive

 

Huh....I tried it after I bored my tb and I didn't notice it running any differently trying to re-learn.

 

ya, advanced auto here just hands over the code reader and you can clear them no problem

 

I guess the ones here are just more strict, because i've tried that at a few different places, and none of them will let me do that.

 

yea they wont let me clear em either. i have fixed 2 of the 3 problems. i fixed the two that i need to pass emissions and the codes havnt gone away. but have been fixed for about 2 days now. but since the codes are still there i cant pass. and i have no way to clear them manually.
