I have a customer with a 04 Tibron,we need to hook up a A/F gauge.The dealership here in town wont help us out.I need the wiring diagram for the ecu.I have seared on the net and cant find anything.Any help is greatly appreciated.

 

Hmm - I'm assuming it's a standard 4 wire heated oxygen sensor. If so, shouldn't you just be able to measure the voltage on the wires. It's probably a narrowband, so I'm thinking It would operate between 0 and 1V. I'm pretty sure mine is at about 350mV at a stoichimetric ratio.

 

Its a v6 and I think there are 4 o2's.I just dont want to screw up anything.Thanks,I may have to go that route.
