Test 15D - Open Ambient Temperature Sensor Circuit
CAUTION:
Always turn ignition off prior to disconnecting or connecting any module connector.
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION . For wiring diagram, see WIRING DIAGRAMS - 3.0L
article in ENGINE PERFORMANCE. Perform TEST VER-1 after each repair.
- Turn ignition off. Disconnect ambient temperature sensor connector, located behind right front bumper fascia. Connect a jumper wire across both ambient temperature sensor connector terminals. Using scan tool, check 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.
- Turn ignition off. 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. Go to next step.
- Using scan tool in ohmmeter mode, check resistance of 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, check resistance of 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.
