TEST 46C - Oil Pressure Sensor Circuit
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION . For appropriate wiring diagram, see WIRING DIAGRAMS .
NOTE:
This test is for vehicles equipped with an electronic instrument cluster.
- Observe electronic instrument cluster. If oil warning indicator (oil can symbol) is flashing, go to step 5). If oil warning indicator is not flashing, turn engine off. Turn ignition switch to ON position. Disconnect oil pressure sending unit connector. Connect a jumper wire between terminal No. 1 (Gray/Yellow wire) of oil pressure sending unit connector and ground.
- Using DRB-II, read oil pressure sending unit voltage. If DRB-II displays less than one volt, replace oil pressure sending unit. Perform VERIFICATION TEST - VERIFICATION OF REPAIRS . If DRB-II displays more than one volt, turn ignition switch to OFF position. Disconnect body controller Blue connector. Body controller is located under left side of instrument panel.
- Check connector, and clean or repair connector as necessary. Reconnect body controller Blue connector. Connect a jumper wire between terminal No. 11 (Gray/Yellow wire) at wiring harness side of body controller Blue connector and ground. Turn ignition switch to ON position.
- If DRB-II displays less than one volt, repair open Gray/Yellow wire. Perform VERIFICATION TEST - VERIFICATION OF REPAIRS . If DRB-II displays more than one volt, replace body controller. Perform VERIFICATION TEST - VERIFICATION OF REPAIRS .
- If oil warning indicator (oil can symbol) is flashing in step 1), turn engine off. Turn ignition switch to ON position. Disconnect oil pressure sending unit connector. Observe electronic instrument cluster. If oil warning indicator (oil can symbol) is not flashing, replace oil pressure sending unit. Perform VERIFICATION TEST - VERIFICATION OF REPAIRS .
- If oil warning indicator is flashing, turn ignition switch to OFF position. Disconnect electronic instrument cluster connector. Check connector, and clean or repair connector as necessary. Put DRB-II in ohmmeter mode.
- Probe terminal No. 2 (Gray wire) of oil pressure sending unit connector. If resistance is more than 5 ohms, replace electronic instrument cluster. Perform VERIFICATION TEST - VERIFICATION OF REPAIRS . If resistance is less than 5 ohms, repair short to ground in Gray wire. Perform VERIFICATION TEST - VERIFICATION OF REPAIRS .
