Hi,

I'm not sure exactly what you are looking for, but I did attach the wiring schematic related to both the intake and exhaust camshaft sensors.

I highlighted the wiring between the sensors and the powertrain control module so you can follow them easier.

Let me know if this is what you needed.

Take care,

Joe

See pics below. Note: I had to cut the page in half to make it readable for you. I did overlap them so you can follow from one to the next.

Thank you much! On the 3-wire connector I'm getting 5.1v on pin A, Pin B is ground, and pin C is reading 5.2v. Well either pin A or C should run 12v. I wasn't sure which one is supposed to have 12v. The wire schematic should help greatly. Thanks again.

The sensors receive a 5v reference. If they would get 12v, it would cause sensor failure.

Let me know if that is what you needed.
