Test 103D - Open Oil Pressure Sending Unit Signal Circuit
WARNING: This page is about a different car, the 1995 Plymouth Voyager, 1995 Plymouth Grand Voyager, 1995 Dodge Grand Caravan, 1995 Dodge Caravan, and 1995 Chrysler Town & Country. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION
. For appropriate wiring diagram, see WIRING DIAGRAMS
section at the end of this article. Perform TEST VER-1B after each repair.
CAUTION:
Always turn ignition off prior to disconnecting or connecting any module connector.
- Disconnect oil pressure sending unit connector. Connect a jumper wire between oil pressure sending unit connector terminal No. 1 (Gray/Yellow wire) and chassis ground. Using scan tool, 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, go to next step.
- Turn ignition off. Disconnect Body Control Module (BCM) Natural connector. BCM is located behind left side knee panel. Using scan tool in ohmmeter mode, check resistance of BCM Natural connector terminal No. 11 (Gray/Yellow wire). If resistance is less than 5 ohms, replace BCM. If resistance is more than 5 ohms, repair open in Gray/Yellow wire.
