Oil Pressure Gauge
NOTE:
After changing checker resistance value, allow 2 minutes for needle to stabilize. Allowable limit of needle deflection is twice width of needle.
- Disconnect oil pressure sensor/switch connector. Connect Red wire lead of Checker (49-0839-285) to oil pressure sensor/switch connector terminal. Connect checker Black wire lead to ground.
- Turn ignition on. Set checker to specified resistance value. See OIL PRESSURE GAUGE RESISTANCE . If oil pressure gauge needle rests at specified position for each resistance value setting, replace oil pressure sensor/switch. If oil pressure gauge needle does not rest at specified position for each resistance value setting, check wiring between oil pressure sensor/switch and instrument cluster. If wiring is okay, replace oil pressure gauge.
