The oil pressure switch detects the engine oil pressure and transmits the oil pressure switch signal to the IPDM E/R.

1. CHECK OIL PRESSURE SWITCH CIRCUIT 
   1. Ignition switch OFF.
   2. Disconnect IPDM E/R connector and oil pressure switch connector.
   3. Check continuity between IPDM E/R harness connector and oil pressure switch harness connector.

      IPDM E/R		Oil pressure switch		Continuity
      Connector	Terminal	Connector	Terminal
      E122	42	E211	1	Yes

   4. Check continuity between IPDM E/R harness connector and ground.
