Manufacturer part number AX355.
What does the AX355 sensor do?
It measures the outside air temperature and sends that reading to the vehicle's climate/body control module, which uses it for the outside-temperature display and to help manage automatic climate control.
Will this fit my vehicle?
It's a direct-fit replacement for 34 GM applications, including many Buick, Cadillac, Chevrolet, and GMC models from 2014-2024. Check the Buyer's Guide tab to confirm your exact year, make, and model.
What are the signs this sensor may need replacing?
Common signs include an inaccurate, stuck, or erratic outside-temperature display or automatic climate control that runs too warm or too cold. Diagnose the cause before replacing, as other faults can cause similar symptoms.
Is this the same as an intake air temperature sensor?
No. This is an ambient air temperature sensor that reads outside air for the climate system and temperature display; it is not the intake air temperature sensor used for engine air management.
