How are Air Conditioning Evaporator Temperature Sensor issues diagnosed?

The first step to identifying an issue with the temperature sensor is to identify if it is functioning properly. This can be done by measuring the air temperature coming from the vents inside the vehicle, and comparing those readings to the sensor readings in the vehicle. If the readings match, the sensor is likely functioning properly. However, if an incongruence exists between the readings, the sensor will be replaced once the circuit is verified to function properly.

How are Air Conditioning Evaporator Temperature Sensors replaced?

Most often, the evaporator temperature sensor can be accessed underneath the instrument panel or behind the glove compartment. However, this is not always the case, and in some vehicles the dashboard will need to be removed partially or completely to access the sensor. Once accessed, the sensor can be popped out of place or unfastened, and disconnected electrically before being replaced and reconnected. Finally, the system will be tested in the same diagnostic manner to determine if the issue has been resolved.

RepairPal Recommendations for Air Conditioning Evaporator Temperature Sensor issues

Air conditioning issues tend to have the same symptoms, but there are many components that may fail and lead to these symptoms. This being the case, it is imperative that the air conditioning system be diagnosed properly before replacing components. This will prevent frustration and frivolous costs.

What to look out for when dealing with Air Conditioning Evaporator Temperature Sensor issues

Not all vehicles have an evaporator temperature sensor. Some will only deactivate the system based on system pressure or temperature at other positions, so diagnosis is a must. It may be the most helpful to have the service manual for the vehicle on hand to allow proper diagnostic procedures to be taken.

Can I replace the Air Conditioning Evaporator Temperature Sensor myself?

Diagnosing the sensor is ideally performed with a diagnostic scan tool and a IR thermometer. However, since most people do not have the expensive scanning equipment, a multimeter can be used to diagnose the temperature sensor as long as the voltage specifications and vent air temperature are known. If this proves to be a challenge or impossible, we advise allowing a certified air conditioning technician handle the repair.
