Allrighty well i kept a p0141 code and a few other codes that relate to my o2 sensors. So i bought both upstream and downstream 02 sensors. Both of those ran me about 100 bucks together or so. So i replaced them about a week and a half or so ago and now im getting a P0141 code again which is O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2). So Should I try and get the 2nd o2 warrentied through Advanced auto or is there something else wrong with my truk?

Disconnect the negative terminal on your battery for ten minutes. This will hopefully clear the codes and do a soft reset of the computer. Worked for me when I had changed my sensors.

Are you running headers or no cat? If the sensors aren't getting hot enough, you can throw this code. I usually just put a block on them. Won't hurt anything.

Yes hashnrown1087...there is a provision in the PCM program that will effectively allow the first 02 sensor to be cancelled-out. I do think it is referred to as CAT Delete. It has solved many a CEL problem with folks in the Houston Chapter. I would suggest PM'ing Stocker2...he is our club tuner! :wink:
