This is for a '96 with a 351. It appears to be running fine. However, my inspection is due and Houston being a smog place has these new strict emmision inspections, so I have to fix this. I have my handy dandy ODB II code scanner and I figured out what the code is; PO141, Bank 1 sensor 2 heater circuit malfunction. Per the Chiltons: Heated Oxygen Sensor Heater (HTR 12) circuit malfunction. I know I have two O2 sensors on the pipe. Does the "HTR 12" mean a specific sensor, or am I totally off base with this?:confused:

you need to check the heater relay, wiring, and connectors, if all okay, then the HEGO sensor is bad. I'm pretty sure all the HEGO's are heated on the same circuit

Hook, line and sinker......... I thought you would sniff out this post. I heard you were the one for this stuff, but I could not remember your nickname. You're talking about the wires and connector right at the sensor, correct? What about the heating relay? Is that also the sensor? Thanks!!:thumbup
