Oil Pressure Switch
Also Known As: Oil pressure sensor, oil sender, oil pressure sender, oil sensor, OPS
Location:
The oil pressure switch may be located on the motor threaded into the engine
block. Part location can be in many locations around the motor block, contact technical
services for part location on your specific application.
What It Does:
The Oil Pressure Switch reports the engine operating oil pressure either to
the dash board light or gauge, and it may also report to the engines computer system for
proper control of the engines other operating systems. The oil pressure switch may also
contain a switch for the fuel pump electrical system. If the engine oil pressure should
become too low during a period of operation, the switch will turn the fuel pump off to
prevent extensive damage to the engines mechanical components.
Failure Symptoms: Oil pressure light illumination, no start condition no fuel pump
operation as the result of low oil pressure, no start condition no fuel pump operation as
the result of a failed oil pressure switch, oil leak from the electrical connector or switch
crimp area.
