119927, 2 code 21's and a new o2 sensor?
Posted by spartan, Feb-23-07 09:33 AM
Gotta another problem after I fixed my code 31. Now I have had 2 code 21's for two weeks now. p1035 heated o2, and high voltage? So I ordered a denso o2 sensor and put it in today. The problem should be fixed, but it's still there. What should I look for now? Wiring? Connectors?

If you tried another sensor, it could be a break in the heater wire in the harness somewhere. Which I think are the black/green, or black/red in the harness. I can't remember off the top of my head.

THe car isn't running bad is it? Shouldn't.

No, the car is running great. That is what is so confusing to me. I guess I will try and take a look, but damn I really don't feel like pulling away all of that wire loom to try and find a broken wire.

If it's running fine, then you can take your time and find out what is wrong.

The heater wire is still the only thing coming to me atm. Good luck.

Get the car scanned for a P code. the 2 digit codes do not tell you much. We can help you more with the P code.

I did that when I was at autozone after I put the new sensor in. Both codes were P1035 one said something about high voltage and I couldn't get a look at what the other code said.

Ok I am going to try and dig into this tomorrow afternoon, any hints on what I should be looking for? Cracked or broken wires? Should I start at the connector and work my way to the ecu pulling the loom apart? Any help is appreciated...
