Started tearing into my lq4 today. As I was taking the harness off and identifying and labeling sensors and such, I found one that I'm not quite sure what it is.
This is motor is kind of a mystery, I bought it already pulled from the vehicle and was told it was from a 2005 2500. As I started looking more into it it seems that it is actually 2002-2003 model, according to the PCM.
Anyway, the sensor in question is on the passenger side of the block just above the oil pan, in the rear (pic below). I think it is the crankshaft position sensor, but the reason I'm not sure is that I have no oil temperature sensor. According to the source I have, the oil temperature sensor should be on the driver side block just under the exhaust manifold; however, on my motor all I have is the oil cooler lines in that area. Anyone have any idea?
