WHY IS THE OIL PRESSURE GAUGE PAST THE HIGH MARK. on 2004 Chevrolet Monte Carlo

WOULD IT BE THE GAUGE. CAR RUNS FINE.

Asked by for the 2004 Chevrolet Monte Carlo
LS? SS? 3.4? 3.8? OH WELL EITHER WAY FIND AND UNPLUG OIL PRESSURE SWITCH,OR SENDING UNIT NEAR OIL FILTER, GAUGE SHOULD NOW READ 0 WITH KEY ON.
IF NOT COULD BE SHORTED WIRE OR BAD GAUGE. CAN SCAN OR HAVE B.C.M. SCANNED TO CHECK DASH CLUSTER.
B.C.M. = BODY CONTROL MODULE. GAUGES DO GIVE TROUBLE! ONE MORE THING, DOES THE GAUGE MOVE AT ALL? AT ANY TIME KEY ON OR OFF.

most likely the oil sending unit is malfunctioning
check oil pressure with gauge....too high = restriction in oil galley...normal = bad sensor or wiring.
