The guage does not seem to be working properly. The engine seems runs fine, I don't feel any difference, but the guage goes from one extreme to the other showing I have no pressure, to going to the high end, then to the middle. It's not consnstant.

What are the telling signs if I am having problems?

Unusual noises such as knocking, burning smells from engine compartment and poor engine performance are all signs of low or no oil pressure.

I would suspect a faulty oil pressure sending unit. This is the device that sends signals to the computer telling the gauge what to show.
