Need help fast...........oxygen sensor signal wire
2001 CL Type S
Installing an air/fuel gauge, the car has a 4 wire Denso heated o2 sensor. I am 99% sure the 2 black wires are for the heater, the white wire is (+) and the green wire is (-). I just want someone to confirm or correct me. Also if anyone knows the pin for this wire at the computer that would be just peachy too.
TIA

Re: Need help fast...........oxygen sensor signal wire
Ok cool, now for the next issue..........which wire it is at the ECU. We tapped all the solid white wires at the ECU but couldnt get continuity from the o2. Is the signal wire color/tracer different at the computer?

Re: Need help fast...........oxygen sensor signal wire
Well there are usually only 2 or 3 shielded cables coming into the ECU harness, one of those is the O2 sensor.. Youl obviously have more than one O2 sensor because you have an OBD2 car. But I'm glad you found it though..
