Removal
1. Remove the oil pressure SW .
2. Remove the nipple; oil gallery.
3. Remove the nipple; oil pressure warning SW and gasket.
Inspection
Check the continuity between the switch terminal and
the body grounding in a no-load condition.
If there is no connectivity, replace with normal parts.

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.
