Cabin Air Temperature Sensor for Ford Climate Control

Standard Ignition AX478 is a direct-fit cabin air temperature sensor built for OE-style fit, form, and function. It is made with durable materials for demanding under-dash conditions and is tested for reliable HVAC performance in Ford applications.

Key Features

  • Direct-fit OE replacement for straightforward installation
  • Black housing with square, plug-in female connector
  • 2 blade terminals for factory-style electrical connection
  • No mounting bracket or wiring harness included
  • Built for consistent cabin temperature sensing in HVAC systems
  • Standard Ignition AX478 for Ford GT and Mustang applications

Product Details

This cabin air temperature sensor helps the climate control system read interior air temperature accurately so the HVAC module can manage heating and cooling response. Standard Ignition AX478 is a direct replacement for select Ford GT and Ford Mustang models, including 2018-2020 Ford Mustang with dual zone climate control and 2017-2020 Ford GT. It also fits 2015 Ford Mustang built to 07/16/2015. This part cross-references Ford FL3Z19C734A and YH1947 for the same application.

What It Helps Solve

  • Incorrect cabin temperature readings
  • Uneven HVAC output in dual zone systems
  • Climate control response delays
  • Faults caused by a worn or damaged interior temperature sensor
  • Fitment issues from non-OE-style replacement parts

Installation Notes and Tips

Verify connector shape, terminal style, and vehicle build date before installation. AX478 uses a direct attachment method with a female square connector and male blade terminals, so it plugs into the factory harness without a separate wiring harness. Confirm the vehicle is equipped with the listed climate control configuration, especially on 2018-2020 Mustang models with dual zone climate control and 2015 Mustang vehicles built to 07/16/2015.

Quality Assurance

Standard Ignition manufactures this sensor with complete process control and extensive testing to support reliable operation and consistent performance. The part is built from high-quality materials to withstand harsh operating conditions in the HVAC system.
