I have a 92 chevy cavalier 3.1 engine runs fine but at 1500rpms the oil pressure maxes out the engine sounds fine still no nocking or anything it does this after it warms up I just had an oil change 1 week ago pres. levels after awhile or around 3000rpms


could it be my sensor and

could it be my sensor and where is it located?

check the oil pressure

check the oil pressure switch, near the oil filter, if the switch got damaged, it could be an erratic signal.
