2004 Grand Prix P0107

I have P0107 on non-supercharged 3800. 5 volts reference signal and 51mv
output from MAP sensor. There is oil dripping from sensor. Is this normal?
PCV is new AC Delco 692.

Uh, no, oil dripping from the sensor is not normal. Are you sure you are looking at the MAP sensor?

Yes. On the 3800, the MAP sensor is located above the PCV valve.

The suggested possible causes for a P0107 code are:



Open in the circuit or short to ground
VREF circuit open or short to ground
Damaged BARO/MAP sensor
Damaged PCM

51mV while the engine is off? How does the engine run? What is the reading with the engine running?

The sensor registers 51mv at all times. I realize that value needs
to change as rpm changes. What would cause oil to pass through PCV valve
to get to MAP sensor?
