Step 16 - Inspect Oil Pressure Switch Continuity

WARNING: This page is about a different car, the 2002 Toyota Tundra. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

Oil pressure should be over 24.5 kPa (0.25 kgf/cm² , 3.55 psi).

If operation is not as specified, replace the switch.

Disconnect the connector from the switch.
Check that continuity exists between terminal and ground with the engine stopped.
