O2 Sensor
I have an 02 GT with 94k on it. I just replaced my downstream O2 sensor in April and now I am getting the CEL P0141 again. Could my sensor be bad again already. I purchased a Standard brand one. Is this a bad sensor and should I just replace with AC Delco instead.

Re: O2 Sensor
Unfortunately it is very possible that the sensor is bad again. Standard sensors are just as good as any other but AC Delco are recommended for GM cars. Try Rock-auto.com for a better price on the sensor if you choose to replace it again.

Re: O2 Sensor
This is a code for the heater ckt to the O2 sensor....make sure that you have power.....could be blown fuse or damaged harness....
If ok, and ground is ok, need O2 sensor....
