The 'oil can' autocheck warning recently began coming on when the rpm's go over 1500. This began after R&R of the steering rack. I replaced the oil pressure switch which is mounted next to the A/C compressor and oil filter but that has no affect. I have checked the electrical connections to it and it is definitly not that circuit that is causing the problem.

Other than the oil temperature sensor, I can find no other sensors that have anything to do with the oil. My car does not have the oil pressure guage so that sensor is not on the car.

The engine sounds fine throughout all rpm ranges and I know what a 'starved' engine sounds like. I believe that it is an Autocheck glitch but I can't figure out why it only occurs over 1500 rpm. The car can idle all day without the warning light.

Any ideas?
