Story about 5 "broken" sensors and broken oil switch connector.

I got 5 codes for 5 bad sensors, this is what happened:
5 sensors, including oil switch, get 5V from PCM. Every sensor has its own wire, but 5 wires are connected together inside PCM. Oil switch connector broke, shorted 5v wire and all 5 sensors stopped working!!! I went to junk yard, removed 6-7 connectors and only 2 of them were good! I guess, this is common GM problem, bad oil switch connectors.

You should be able to buy the connector shells and terminals from Mouser Electronics after you determine what they are... The part numbers are in the FSM.
