Oil Pressure Sensor: Testing and Inspection

ENGINE OIL PRESSURE SWITCH TEST

1. Remove the YEL/RED wire from the engine oil pressure switch.
2. Check for continuity between the positive terminal and the engine (ground) with the ignition switch OFF.

-

If there is continuity, go to step 3.

-

If there is no continuity, replace the switch.

3. Check for continuity again, this time with the engine running.

-

If there is continuity, go to step 4.

-

If there is no continuity, the switch is OK.

4. Make sure engine oil level is OK, then check engine oil pressure.

-

If engine oil pressure is OK, replace the switch.

-

If engine oil pressure is low, check the engine oil pump and, if necessary, replace it.
