Oil Pressure Sender: Testing and Inspection

1. Raise the car, and place safety stands in the proper locations. (See General Information).
2. Remove the right rear tire.

Engine Oil Pressure Switch Test:

3. Remove the YEL/RED wire from the engine oil pressure switch.
4. Check continuity between the positive terminal and engine (ground) with the engine off.
- If there is no continuity, the switch is OK.
- If there is continuity, do not replace the switch; first check other possible causes in step 6.
5. Make sure engine oil level is OK, then check engine oil pressure (See Engine Lubrication).
- If engine oil pressure is OK, replace the engine oil pressure switch.
- If oil pressure is low, remove, inspect, and, if necessary, replace the oil pump (See Engine Lubrication).
