Ambient Temperature Sensor / Switch HVAC: Testing and Inspection

Ambient Temperature Sensor, A/C

NOTE: Sensor resistance drops with increasing temperature.








Check Sensor
- Use ohmmeter. Carry out measurement at room temperature approx. 2O-23 °C (68-73 °F). Ignition should be switched OFF.
- Resistance: 30 - 40 Ohms.
- If resistance is much higher: 65 - 100 Ohms, replace sensor.
