Sensor Circuit Test
Sensor Circuit Test1. Turn the ignition switch to the OFF position.
Unplug the temperature sensor connector.
2. Connect a jumper wire between the two terminals in the body half of the sensor connector.
3. Remove the overhead console.
Disconnect the overhead console wiring connector.
4. Check for continuity between the sensor ground circuit and the ambient temperature sensor signal circuit cavities of the overhead console connector. There should be continuity.
If OK, go to Step 5.
If not OK, repair the open circuit as required.
5. Remove the jumper wire from the temperature sensor connector.
Check for continuity between the sensor ground circuit cavity of the overhead console connector and a good ground. There should be no continuity.
If OK, go to Step 6.
If not OK, repair the short circuit as required.
6. Check for continuity between the ambient temperature sensor signal circuit cavity of the overhead console connector and a good ground. There should be no continuity.
If OK, see the diagnosis for the Compass/Display Module. Testing and Inspection
If not OK, repair the short circuit as required.
