Ambient Temperature Sensor Circuit Short

NOTE: After making any repairs, perform BODY VERIFICATION TEST  under VERIFICATION TESTS.
  1. Turn the ignition off. Disconnect the ambient temperature sensor harness connector. Measure the resistance of the ambient temperature sensor. See AMBIENT TEMPERATURE SENSOR RESISTANCE  table. If the ambient temperature sensor resistance is within the min/max specifications, go to next step. If the ambient temperature sensor resistance is not within the min/max specifications, replace the ambient temperature sensor.
  2. Turn the ignition off. Disconnect and isolate the negative battery cable. Disconnect the ambient temperature sensor harness connector. Disconnect the compass/temperature mirror harness connector. Measure the resistance of the ambient temperature sensor signal circuit between the sensor connector and ground. If the resistance is less than 5.0 ohms, repair the ambient temperature sensor signal circuit for a short to ground. If the resistance is more than 5.0 ohms, go to the next step.
  3. Turn the ignition off. Disconnect and isolate the negative battery cable. Disconnect the ambient temperature sensor harness connector. Disconnect the compass/temperature mirror harness connector. Measure the resistance of the ambient temperature sensor ground circuit between the sensor connector and the compass/temperature mirror connector. If the resistance is more than 5.0 ohms repair the ambient temperature sensor ground circuit for an open. If the resistance is less than 5.0 ohms, replace compass/temperature mirror.
