OK, after a full days driving, got a CEL. I MAY have mixed up the O2 sensors locations installing the new cats. By any chance can anyone tell me which sensor goes in which position? I currently have the the sensor with the GRAY wiring cover installed AFTER the cat, and the sensor with the BLACK wiring cover installed BEFORE the cat, just after the turbos. Right? Wrong?

Cheers

thats correct... make sure both sides are the same..
Im guessing its the cat thats causing the issue...

 

Agree.

OP: what is the error code associated with the CEL?

 

Durametric shows:

P1145 O2 sensor ahead of cat conv. Cylinder (1-3) exceeds limit value

P1155 O2 sensor ahead of cat conv. Cylinder (4-6) exceeds limit value

So, does that mean I actually DO have the O2 sensors mixed up?

Cheers

Mike,

The 02 sensor's with the black/grey/white wires are for the rear. The color coded wires are the ones that go in the front.

Lift yo the cover's and you will be able to see the wires... Sorry for not getting back to you earlier. I willl shot you an email right now.

 

Thanks Enrique! I'll take a look again tonight, I'm thinking I may have em both backwards. I'll update you on progress.

Cheers
Mikey

 

Quick- did you get this reconciled??
thanks.

Yep, Enrique got me fixed up. Wow, that was over a year ago.
