❄️ Back to Cool Drives — A/C Evaporator Temperature Sensor 6G91-19C734-AA
A/C Evaporator Temperature Sensor
Bring Back the Cool.
Start with the Right Sensor.
Cold air that fades halfway through your drive? When a faulty evaporator sensor is the cause, replacing it helps restore the temperature feedback your A/C needs to keep cooling properly.
Small Part. Important Job.
Help Your A/C Keep Its Cool
The evaporator sensor monitors temperature and sends feedback to the vehicle’s climate-control system. That feedback helps the system manage compressor operation and reduce the risk of evaporator icing.
A failing sensor can contribute to frustrating changes in cooling:
- Cold air turns warm: cooling fades after the A/C has been running.
- Airflow drops: ice on the evaporator can restrict air passing through it.
- Cooling becomes inconsistent: the system receives incorrect temperature information.
These symptoms can have more than one cause. Confirm a sensor fault before choosing a replacement.
