Oil Pressure Switch
Inspection
Check the continuity between the switch terminal and
the body grounding in the no-load condition.
If there is no connectivity, replace with normal parts.
(Refer to “Oil Filter Assembly”)
Circuit check
1. Turn the starter switch to ON.
2. Disconnect the oil pressure switch connector, and
confirm that the oil pressure-warning lamp lights
when the connector on the harness side is
grounded.
If the warning lamp does not light up, check the
circuit between the meter and the oil pressure
switch, and repair the disconnected locations.
