Gauge Always Indicates High Oil Pressure
- Disconnect fuel pump/oil pressure switch/sender connector. Turn ignition on. Connect fused jumper wire between Tan wire at fuel pump/oil pressure switch/sender connector and ground.
- If oil pressure gauge indicates low pressure or indicator lights, replace fuel pump/oil pressure switch/sender. If oil pressure gauge indicates high pressure or indicator does not light, locate and repair open circuit in Tan wire between fuel pump/oil pressure switch/sender connector and instrument cluster connector. If wire is okay, replace instrument cluster.
