i know what the codes are and i have already replaced the o2 sensor on the y-pipe section nearest the firewall, but how the hell do i fix the p0138 code? it keeps reading that code on the bank 1 sens 2, help me help me palease!!

 

Have you disconnected the battery over night after replacing the sensor? If you did not, the codes will keep coming up...

 

Just disconnect the battery when you get to work, and it should be ready when you leave in the morning

 

been there tried that, its not resetting. even after i had discount reset it it came back up.

 

did you replace the post cat o2 sensor?

and... have you had the PCM reprogrammed.

 

cat o2 gets replaced tomorrow along with the final o2 (bank 2)

 

How long did you leave the battery off for? It's supposed to be overnight. Somewhere on here I read > 24 hrs...

 

in my past experiences i didnt have to leave it off for 24 hours, the last time i did it, it was for no longer than like 4 hours (possibly more, dont remember). that always seems to reset my codes with no prob.

is there a possibility that some codes cant be reset in the shorter timespan? maybe o2 codes require the 24 hours while the others dont?

 

erasing volatile memory usually doesnt take longer than 15 seconds, on some cars it might be longer, but not in the 'hours'

this of course doenst apply to older cars.

 

i also pulled those codes. where did u order your O2 sensors from? the best price i found was $109 each

 

Got the BOSCH (OEM) for $70 at Orielly's *spelling* and it should be here Monday I hope!

 

where is that?? any links?? let me know

thanx

 

Oreilly's Auto Parts stores, same quality as an AUTOZONE, but my guess is cheaper, but I only paid $70 so...
