Test 47C - Open Oil Pressure Sending Unit Signal Circuit
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION in this article. For wiring diagrams, see WIRING DIAGRAMS article in this article.
CAUTION:
Always turn ignition off prior to disconnecting or connecting any module connector.
- Disconnect oil pressure sending unit. Connect a jumper wire between oil pressure sending unit signal circuit (Gray/Yellow wire) and ground. Using DRB at oil pressure sending unit connector. Using DRB, read oil pressure sending unit voltage. If voltage is less than one volt, replace oil pressure sending unit. Perform TEST VER-1B. If voltage is more than one volt, go to next step.
- Turn ignition off. Disconnect Natural Body Control Module (BCM) connector. BCM is located behind center console. Using DRB in ohmmeter mode, check resistance of oil pressure sending unit signal circuit (Gray/Yellow wire) at Natural BCM connector terminal No. 22. If resistance is less than 5 ohms, replace BCM. Perform TEST VER-1B. If resistance is more than 5 ohms, repair open in Gray/Yellow wire. Perform TEST VER-1B.
