switch, an oil pressure test has to be
performed. If the engine oil pressure is good,
check the resistance of the oil pressure switch
while engine is off and while engine is running.

Oil Pressure Switch Test

▪ Disconnect the connector from oil pressure
switch.
▪ Use multimeter to check the continuity.
▪ Replace the oil pressure switch if necessary.
▪ If OK, check the continuity of the wiring
harness.
