Test 47E - Open 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. Connect a jumper wire between oil pressure sending unit signal circuit (Gray/Yellow wire) and ground. Using DRB-II, read oil pressure sending unit voltage. If voltage is less than one volt, replace oil pressure sending unit. If voltage is more than one volt, 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, replace body controller. If resistance is more than 5 ohms, repair open in Gray/Yellow wire.
