So I came to notice today that the wire for my o2 sensor is dangling and somehow came unclipped. The sensor itself is still plugged in, but the wire came unclipped and now just drags against the road. The gray wire cover/loom had been destroyed and I could see the wires through.

I electrical taped it up and will attempt to reattach it (i don't have jacks, stands, or access to a lift and my car is lowered)

I have 2 questions...

1. If the wires were messed up so bad, would it throw a CEL?

2. Anyone know what I can attach the wire back to?

 

Well you have a Cobb AP so it's probably turned the CELs off for that rear sensor. Depending on the wire clipped, if the o2 heater circuit was turned off then the rear sensor is probably damage, but since all the rear o2 measures is the cat efficiency, it's not a big deal.

 

Yeah I guess I won't know if it has turned off or not, but I was able to successfully tuck the wire away so at least it's not dangling anymore.

 

find a high curb to pull your car up onto, or guess what, you have a jack in your trunk

Tape it up and get it back up into position, not gonna be nice if it gets caught on something!

 

Already fixed, didn't even have to take it up on a curb! I was able to reach and tuck it under a metal panel, wire is clear of the DP and is tucked firmly away to where it shouldn't come loose. I'll keep an eye on it, thanks for the suggestions!
