Test 56D - Repairing Open Ambient Temperature Sensor Circuit
WARNING: This page is about a different car, the 1994 Chrysler LeBaron. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
For connector terminal identification, see CONNECTOR
IDENTIFICATION. For wiring diagram, see WIRING DIAGRAMS
. Perform TEST VER-1 after each repair.
CAUTION:
Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
- Turn ignition switch to OFF position. Disconnect ambient temperature sensor connector, located on inside left front bumper. Connect a jumper wire across both ambient temperature sensor connector terminals. Using DRB, measure ambient temperature sensor voltage. If voltage is less than 0.2 volt, replace ambient temperature sensor. If voltage is more than 0.2 volt, go to next step.
- Disconnect jumper wire. Disconnect compass/temperature module connector, located behind overhead console. Connect a jumper wire across both ambient temperature sensor connector terminals to ground. Put DRB in ohmmeter mode. Measure resistance at compass/temperature module connector terminal No. 6 (Violet/Light Green wire). If resistance is more than 5 ohms, repair open in Violet/Light Green wire. If resistance is less than 5 ohms, go to next step.
- With jumper wire still connected, measure resistance at compass/temperature module connector terminal No. 8 (Black/Light Blue wire). If resistance is more than 5 ohms, repair open in Black/Light Blue wire. If resistance is less than 5 ohms, replace compass/temperature module.
