Oil Pressure Switch
The engine oil pressure switch is located on the engine
above the starter motor (Fig. 59). The oil pressure
switch is a normally closed switch that opens with pres-

The oil pressure switch should open at approximately 8
PSI (0.56 kg/cm

).
The TEC controller monitors the operation of the oil
pressureswitch. Theswitchand itscircuit wiringshould
be tested as a controller input with the Diagnostic Dis-
