Detailed Description

This Dorman ambient air temperature sensor, part number 902-021, is engineered to restore accurate outside air temperature readings for the vehicle’s HVAC system. It is built with a plastic housing, round connector shape, and threaded installation point to match the original sensor layout on supported applications. This part cross-references Delphi TS10541 for the same application. Compatible with Ford F-150, Ford Explorer, Lincoln Navigator, and Mercury Grand Marquis applications, 902-021 is a direct replacement choice for vehicles that rely on a properly functioning ambient temperature signal.

What It Helps Solve

• Incorrect outside temperature display
• HVAC system behavior affected by a faulty ambient sensor
• Temperature readings that fluctuate or read inconsistently
• Loss of accurate input for automatic climate control logic
• Replacement needs after sensor housing or connector wear

Installation Notes and Tips

Verify connector style, thread diameter, and mounting location before installation. This sensor uses a threaded mount and a 2-terminal bullet connection, so the vehicle-side connector and sensor opening should match the original configuration. Confirm fitment by year, make, and model before ordering.
