TESTING



See Figures 3 and 4

The low oil pressure warning lamp will illuminate when the ignition switch is turned to the ON position without the engine running. The lamp also illuminates if the engine oil pressure drops below a safe oil pressure level. To test the system, perform the following:

  1. Turn the ignition switch to the ON position.
  2.  
  3. If the lamp does not light, check for a broken or disconnected wire around the engine and oil pressure sending unit switch.
  4.

  1. If the wire at the connector checks out OK, pull the connector loose from the switch and, with a jumper wire, ground the connector to the engine.
  2.  
  3. With the ignition switch turned to the ON position, check the warning lamp. If the lamp still fails to light, check for a burned out lamp or disconnected socket in the instrument cluster.
