Hey guys, my o2 sensor wire from the ecu to the sensor is coroded to crap and my o2 sensor isn't reading so which wire/pin in the plugs at the ecu is the 02 sensor wire?

A diagram would help but any info is always good! THanks

Pin 2D Middle connector, bottom row, second from left. TIme to get the fsm dude!..........

 

Disregard the Ground In the diagram.



Don't listen to J-Rat...he's bad news.

 

He has an S4 car dummy...

 

...that hurt. Under normal circumstances that Is punishable by a beating, but In your case - your forced to live with your username.

I provided the diagram for both s4 and s5's for any onlookers that want to know for their given car aswell.

 

I'll assume you meant 2nd from the right aswell.

 

Thanks alot Guys! You are all a big help

 

This and other ECU pin-out questions come up often so I did a little drawing to help you all out. You should still use the FSM to confirm wire colours.
