Detailed Description

This Dorman ambient air temperature sensor is engineered for direct replacement service on a wide range of GM vehicles. The sensor measures ambient air temperature and sends that data to the vehicle’s HVAC and instrument systems, helping maintain accurate outside temperature readings. Part number 902-026 is listed for applications such as 2014-2021 Chevrolet Silverado 1500, 2014-2021 GMC Sierra, 2017-2021 Cadillac XT5, and 2018-2021 Chevrolet Equinox, along with many other Buick, Cadillac, Chevrolet, and GMC models.

The sensor uses a copper sensing element, a female connector, and a clip-on mounting style. Its oval connector shape and 2-terminal layout support a clean OE-style replacement on vehicles that use this configuration. This part cross-references Standard Ignition AX355 for the same application.

What It Helps Fix

• Incorrect outside temperature readings on the dash
• HVAC temperature display errors
• Faulty ambient air temperature signal to the climate control system
• Sensor damage from age, road debris, or weather exposure
• Intermittent temperature readings caused by connector or sensor wear

Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. This sensor uses a clip-on mount and does not include a wiring harness. Confirm vehicle-specific bracket requirements where noted, including Buick Encore and Chevrolet Trax applications with bracket.
