Hello and Welcome to Justanswer, My name is XXXXX XXXXX I am here to try and assist your with your question
the o2 senor is the front one on the exhaust manifold
check it for power with the key on on the white wire going to the 02 sensor
You are missing the power to the 02 sensor to heat it up
I have not had the chance to check the power on the white wire for the 02 Sensor. Wanted to ask a followup question about if there is no power for the heater on the 02 Sensor, should I just replace the PCM with a used one from a junk yard? I think there is a pin on the PCM to check for power also but wondering how much I can do with just a Sears omh meter.
the power comes from the fuel injector fuse. If the engine is running the fuse is good
if there is no power to it then you have a open wire and you need to trace it find the break in the wire harness
check at the connector pull on the wire and see if it breaks or is broken
