I got the code 156 (thats what the auto zone guy wrote down) I think it was P0156 if that makes any difference. It said Bank 2, Sensor 2. The computer said there were two codes, but it was this one twice. What does it mean? Thanks in advance. Oh, and its a 97 cobra in case my sig didn't give that away... :D

P0156 HO2S Circuit Bank 2 Sensor 2 Generic OBDII Code is all it says....

Looks like an O2 sensor is bad, not sure which one though...I think bank2 is driver side so Bank 2 Sensor 2 may be the rear driverside sensor ?? (just a guess).

That code is the aft driver side 02 sensor. Good guess Tom ;)

Can I buy the sensor online cheap anywhere and replace myself?

I think last time I got a similar code about a sensor and autozone said the dealer would have to change it.


Thanks for all the quick replys.

You can get an 02 sensor from autozone. It's a rear 02 sensor, so it doesn't do anything really. It's easy to change out.
