How do i know which wire is the signal wire on the o2 sensor for a ?
My mechanic said he believes the ecm is shorting out my O2 sensors (3 in two months) I replaced the ecm with a used one but before I put the new sensor in I want to make sure the voltage isn't to high causing it to short yet another one.
Thanks a bunch

ECM don't short out sensors but sensors can cause the ECM to fail. If the quality of the sensor is suspect, they would not last.
There are 2 HO2S, whcih is faulty?
What were the trouble codes you were getting?

It is the one above the catalytic converter. The trouble code was O2 sensor bank one. I just have a simple scanner and that's all ti says.

I need the EXACT code. O2 sensor has 2 circuits in them and if it is the heater side that has faile, the power supply is from battery and not linked to the computer.
