Oil pressure gauge is not working.
How can I tell if it's the gauge or sensor?

Good evening,

The best way to tell is to check the actual oil pressure with a gauge.

You remove the oil sender unit and insert the gauge and measure the pressure. At idle you should 30-35 pounds and at 1200 you should have 45-60 pounds.

I attached the location for you. You can rent a tester at a parts store for the test.
