Outside Air Temperature Sensor Test (With Climate Control)

Outside Air Temperature Sensor Test

NOTE: Before testing, check for HVAC DTCs. How to Troubleshoot the Climate Control System

1. Remove the outside air temperature sensor. Outside Air Temperature Sensor Replacement (With Climate Control)

2. Dip the sensor in ice water, and measure the resistance. Then pour warm water on the sensor, and check for a change in resistance.

3. Compare the resistance reading between the No. 1 and No. 2 terminals of the outside air temperature sensor with the specifications shown in the graph; the resistance should be within the specifications.

4. If the resistance is not as specified, replace the outside air temperature sensor. Outside Air Temperature Sensor Replacement (With Climate Control)
