OIL PRESSURE SENSOR/
SWITCH
DESCRIPTION
The oil pressure switch is located on the right rear
side of the engine block (Fig. 1). The oil pressure
switch is a pressure sensitive switch that is activated
by the engine’s oil pressure (in the main oil gallery).
The switch is a two terminal device (one terminal is
provided to the wiring harness and the other termi-
nal is the switch’s metal housing that screws into the
engine block).
OPERATION
The oil pressure switch changes from an 9Open9
circuit to a 9Closed9 circuit, on decreasing pressure,
between 2 psig and 4 psig. The switch changes from
a 9Closed9 circuit to an 9Open9 circuit, on increasing
pressure, within a maximum of 3 psig of the switch’s
9Closed9 circuit pressure point.
REMOVAL
(1) Raise vehicle.
(2) Position oil collecting container under pressure
switch location.
(3) Disconnect oil pressure switch electrical con-
nector and remove switch (Fig. 2).
INSTALLATION
(1) Install oil pressure switch and connect electri-
cal connector (Fig. 2).
(2) Lower vehicle.
(3) Start engine and allow to run a minimum of 2
minutes.
(4) Shut engine off and check engine oil level.
Adjust level as necessary.
