SWITCH-OIL PRESSURE
DESCRIPTION
The engine oil pressure switch is located on the timing cover, in front of the engine. The normally closed switch provides an input through a single wire to the low pressure indicator light on the instrument cluster.
OPERATION
The oil pressure switch provides a ground for the instrument cluster low oil pressure indicator light. The switch receives oil pressure input from the engine main oil gallery. When engine oil pressure is greater than 27.5 Kpa (4 psi), the switch contacts open, providing a open circuit to the low pressure indicator light. For wiring circuits and diagnostic information, (Refer to Appropriate Wiring/Diagnostic Information).
