Removal & Installation
- Raise vehicle on hoist.
- Position an oil collecting container under switch location.
- Disconnect electrical connector.
- Unscrew oil pressure switch .
- Apply Mopar® Thread Sealant to the switch threads.
- Install oil pressure switch to fitting.
- Connect electrical connector.
- Lower vehicle.
- Start engine and check for leaks.
- Check engine oil level and adjust as necessary.
- Turn ignition ON (engine off ).
- Verify if the oil warning lamp lights.
- turn ignition off.
- Check the engine oil level. Adjust as necessary.
- If engine oil level is within specification disconnect the engine oil pressure switch connector.
If the oil warning lamp goes out:
- Remove the oil pressure switch.
- Connect an oil pressure gauge in its place.
- Start the engine.
If the pressure reading is 4.0 PSI or greater at idle :
Allow the engine to reach normal operating temperature.
If the oil pressure warning lamp doesn-t go out when disconnecting the oil pressure switch connector:
Disconnect the instrument cluster.
- If the oil pressure warning lamp doesn-t light when turning the ignition switch on, disconnect the oil pressure switch connector.
- Connect a jumper wire between the oil pressure switch sense circuit and ground.
- If the warning lamp lights, replace the oil pressure switch.
If the warning lamp doesn-t light, keep the jumper wire connected and disconnect the instrument cluster.
With an ohmmeter measure the oil pressure switch sense circuit to ground:
If the resistance is above 5.0 ohms repair the open oil pressure switch sense circuit between the switch and the instrument cluster.
