Ambient Temperature Sensor

WARNING: This page is about a different car, the 2005 Dodge Grand Caravan, 2005 Dodge Caravan, and 2005 Chrysler Town & Country. However, it is still accessible from the selected car via links, so may be relevant.
  1. Turn the ignition switch to the Off position. Disconnect and isolate the battery negative cable. Disconnect the ambient temperature sensor wire harness connector.
  2. Measure the resistance of the ambient temperature sensor. At room temperature (approx. 68°F), the sensor resistance should be between 10-13 Kilohms. The sensor resistance should be between these two values at 68°F. If the resistance is out of range replace the ambient temperature sensor.
