Oil pressure switch
Apply compressed air (392 kPa/4.0 kg/cm2) to the oil pressure
switch to check the oil pressure switch continuity between the
connector and screw.

Oil temperature sensor (harness assembly)
Check the oil temperature sensor resistance between harness
terminals 7 and 6 (ground).
Oil temperature sensor resistance: 2,400
2,600 ohms
(20
