Just installed a Comptech header and the Invidia exhaust and this cel popped up. I handled the o2 sensor real easy. I cleared it but it just popped back up. Any suggestions?

Thanks,

Thats a bummer. I'm going to assume that you already re-checked all of the connections? I really don't know what else to suggest.

Checked all the connections and everything looks good. Hate to have to replace the o2 sensor. Might see if I can get it into SOS tomorrow.

O2 heater malfuntion. Check the amperage at the O2 sensor heater wire. It should be about .8 amps. If you have an OBDII tool, then you can monitor it by just plugging it in. As long as the O2 sensor works, you are fine. The heater is just to get the car up to temperature quicker so the pcm can start adjusting the A/F ratio and not be in open loop.

Are you running a tp? if so get an O2 sim

It was a blown fuse. Replaced the fuse (didn't look bad)
and cleared the code and it seemed to have fixed the issue.
A big thanks to Boofster (Ivan) for the diagrams.
The man knows his stuff.
