Oil Pressure Gauge Test: Capri
- Remove electrical connector from oil pressure sending unit located on right side of engine block. Turn ignition switch on. Oil pressure gauge should read low. Install a jumper wire between Yellow/Red wire of oil pressure sending unit harness connector and ground. Oil pressure gauge should read high. Connect Rotunda Gauge System Tester (021-00038) to Yellow/Red wire and set to resistance values shown in OIL GAUGE RESISTANCE (CAPRI) table.
- If oil pressure gauge operates as specified, replace sending unit. If gauge does not operate as specified, check instrument panel power and ground circuits.
