Test 47D - Grounded Oil Pressure Sending Unit

NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION  . For wiring diagram, see WIRING DIAGRAMS article in this section.
CAUTION: Always turn ignition off prior to disconnecting or connecting any module connector.
  1. Disconnect oil pressure sending unit. Using DRB, read oil pressure sending unit status. If DRB displays OIL PRS LOW:OPEN, replace oil pressure sending unit. Perform TEST VER-1B  . If DRB does not display OIL PRS LOW:OPEN, go to next step.
  2. Turn ignition off. Disconnect Natural Body Control Module (BCM) connector. BCM is located behind center console. Using DRB, read oil pressure sending unit status. If DRB displays OIL PRS LOW:OPEN, replace BCM. Perform TEST VER-1B  . If DRB does not display OIL PRS LOW OPEN, go to next step.
  3. Turn ignition off. Disconnect instrument cluster connector. Instrument cluster connector is located behind instrument cluster. Using DRB in ohmmeter mode, check resistance of oil pressure sending unit sense circuit (Gray wire) at instrument cluster connector terminal No. 8. If resistance is less than 5 ohms, repair short to ground in Gray wire. Perform TEST VER-1B  . If resistance is more than 5 ohms, replace instrument cluster. Perform TEST VER-1B  .
