Crossed o2 wires
Crossed o2 wires My dad has a 98 trans am and was putting headers on and crossed the o2 wires and now hptuners is reading no volts with brand new sensors any ideas? Could it possibly fry the pcm?
If he's absolutely, positively certain that he got the wires connected correctly it's PCM time.
The only powered circuit on the O2 sensor is the heater. And even without it, you'd still see sensor voltage albeit lazily until the sensor gets up to temp.

Yea the cars running but like ****. It falls on its face. The wiring is correct we bought bosch 13111 you dont have to splice them they are already exteneded and you plug them into the harness.
I have another question though I was looking at a new pcm and they said it needs flashed (reprogrammed) can Hp tuners do this?
