If you're hunting for a Mustang sensor that keeps your engine's computer reading incoming air correctly, the Standard Ignition Engine Intake Manifold Temperature Sensor AX31 is a direct-fit replacement for the listed applications — including the 1996-2004 Ford Mustang, 1997-2008 Ford F-150, 1997-2002 Ford Expedition, 1997-2003 Ford Escort and many more Ford, Lincoln, Mercury and Mazda models. See the Buyer's Guide tab for the full list of vehicles and engines.
This sensor measures the temperature of the metered air entering the intake manifold and reports it to the engine control module, which uses that reading to help trim fuel delivery and ignition timing for the current operating conditions.
- Reads intake air temperature: monitors the temperature of the metered air in the intake and signals the ECM.
- Supports proper air/fuel calculation: gives the computer the data it needs to adjust fueling and timing.
- Direct-fit replacement: installs on the listed applications without modification.
Signs this sensor may need replacing include a check engine light, a related temperature-circuit trouble code, rough running, hard starting, or poor fuel economy. If a failed intake air temperature sensor is the cause, this AX31 replaces it — diagnose the fault before installing.
