Oil Themostat

On those senders a poor connection, poor ground can cause the cold reading (high resistance=low temp. Or its a bad sensor. Since its a new sensor and gauge I'd lean to what Cycleguy mentioned.

PS: over-torquing the center stud can really screw them up permanently. Should be snug enough to prevent the eyelet from swiveling only.

Spoke to Autometer on the phone and they suggested a continuity test from the body of the sending unit to the frame. I already did that and it was fine. Grounded the gauge connection on the sender and the gauge went to max so the gauge is fine. As long as I know the oil is over 200 degrees in the pan I am not going to worry about it till I change the oil and pull the sender. Thanks for the chart. Going to compare laser oil pan reading to sender ohm reading next time I take the car out.
