Hi there,When does the light come on, only at idle?How many miles on this engine?I would be measuring the oil pressure with a workshop gauge.Gary

Can you run me through how do I use an air compressor on the oil pressure to test it also the light comes on whenever I about 4000 RPM or whenever I get on it there's 110,000 miles motor

Ok, first up I would not drive it until you prove the engine is ok.You need a workshop style oil pressure gauge, or even a cheaper mechanical gauge to screw in place of the sensor.Is the oil level correct?Does it make any noise when the light comes on?I would take a bet your issue is not sensor or ECM related.Gary
