Oil Pressure Sender: Description and Operation
DESCRIPTION
The oil pressure switch is located on the right rear side of the engine block (Fig. 118). 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 terminal is the switch's metal housing that screws into the engine block).
OPERATION
The oil pressure switch changes from an "Open" circuit to a "Closed" circuit, on decreasing pressure, between 2 PSI and 4 PSI. The switch changes
from a "Closed" circuit to an "Open" circuit, on increasing pressure, within a maximum of 3 PSI of the switch's "Closed" circuit pressure point.
