Low oil light illuminated with full oil - ZR-1 Net Registry Forums

BlackbirdZ07 · 05-09-2012

I just finished a bunch of work on my '90 including new injectors, etc. Before I started, the low oil light was on but the oil was full. I replaced the oil pressure sensor AND the oil level switch on the oil filter housing with new GM parts. Also changed the oil.

I've added 9.5 quarts and the dipstick indicates that the oil level is at the full mark. I had to add that much because I also removed the oil pan to replace the gasket, so I got all the oil out of the pan. I used Amsoil 10W30.

After all the work and the oil change, the LOW OIL light still comes on when the car is running, but the oil is full. Any ideas why this light is on?
