In-car Temperature Sensor Test

In-car Temperature Sensor Test

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

1. Remove the in-car temperature sensor In-car Temperature Sensor Replacement.

2. Heat and cool the sensor by holding it in front of the dashboard center vent.

- Measure the resistance with the system set to Max Cool.
- Measure the resistance with the system set to Max Hot.

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









4. If the resistance is not as specified, replace the in-car temperature sensor In-car Temperature Sensor Replacement.
