Test 47C - Grounded Oil Pressure Sending Unit Signal Circuit
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION. For wiring diagrams, see WIRING DIAGRAMS
article in the ENGINE PERFORMANCE Section. Perform TEST VER - 1A after each repair.
CAUTION:
Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
- Turn ignition switch to ON position. Disconnect oil pressure sending unit. Using DRB-II in voltmeter mode, read oil pressure sending unit voltage. If voltage is more than 8 volts, replace oil pressure sending unit. If voltage is less than 8 volts, turn ignition switch to OFF position. Disconnect Natural body controller connector. Body controller is located under left side of instrument panel.
- Using DRB-II in ohmmeter mode, check resistance of oil pressure sending unit signal circuit at Natural body controller connector terminal No. 22 (Gray/Yellow wire). If resistance is less than 5 ohms, repair short to ground in Gray/Yellow wire. If resistance is more than 5 ohms, replace body controller.
