Ambient Temperature Sensor Test

WARNING: This page is about a different car, the 2004 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.
  1. Turn the ignition OFF.
  2. Disconnect the ATS harness connector.
  3. Measure the resistance of the ATS using the following min/max values:
    • 0°C (32°F) Sensor Resistance = 29.33 - 35.99 Kilohms
    • 10°C (50°F) Sensor Resistance = 17.99 - 21.81 Kilohms
    • 20°C (68°F) Sensor Resistance = 11.37 - 13.61 Kilohms
    • 25°C (77°F) Sensor Resistance = 9.12 - 10.86 Kilohms
    • 30°C (86°F) Sensor Resistance = 7.37 - 8.75 Kilohms
    • 40°C (104°F) Sensor Resistance = 4.90 - 5.75 Kilohms

The sensor resistance should read between these min/max values. If the resistance values are not OK, replace the Sensor.
