What does it mean, it says O2 Sensor Circuit Bank 1, Sensor 2.

I got a CEL fix with my downpipe, and I did the Resistor for the uppipe so what I am thinking is that the CEL fix for the downpipe is defective...is that true?

Thanks,
Zoeb

EDIT: I dont think the CEL fix is defective since my air fuel ratio gauge used to work, and after putting in the fix it doesn't show a reading anymore...Also can an exahust leak cause the CEL as well, and what do I listen to for an exhaust leak?

Also Thanks to Slack for pulling the code for me!

 

well i dont know how the fixes work.
but usually that means that your O2 sensor went out. or there is something wrong with that circuit

 

The cel fix is probably gone just buy ont through pony express MIL
Leaks sound like a steady hiiiissssssss

 

no an exhaust leak will not throw a cel, i had a major one and it didn't give a cel.

and an exhaust leak is just a hissing noise

 

If you are using the Pony Express MIL eliminator, make sure you have the right wires connected, and make sure they securely connected with butt connectors. I threw a CEL when changing back from my catless to high flow cat, because a loose wire came out of its connector.

Your rear O2 sensor has to be in good working condition for the MIL eliminator to work properly. Also make sure your rear O2 sensor is securely fastened to its mounting point.
