We just finished putting my new engine in the car. Everything is fine, car starts, but when we hooked the scanner, the O2 sensors won't emit any reading.
It's like the PCM is not acknowledging their presence. We probed the O2 sensors wires, and they have some activity (913mv)
We even swapped PCMs but no luck. We checked for broken pins, connectors, and still can't get them to show any reading on the scanner.
If this may help...We took the engine out from underneath, and that meant disconnecting everything. So, I don't know if something was missed.
My mechanic is working on it, so I'm confident he'll nail it down, I'm just a little bit impatient, and I want to help.
