GPD Air Charge Temperature Sensor Direct Fit

The GPD Air Charge Temperature Sensor (also called an ACT sensor, intake air temperature sensor or IAT sensor) is a direct-fit replacement that monitors the temperature of the air entering the engine. It sends this reading to the engine control module (ECM), which uses it to adjust fuel delivery and ignition timing.

Key Features:

• Direct-fit design for straightforward installation, with no modification required
• Thermistor-based sensing element that changes resistance with air temperature
• Supports accurate air/fuel mixture calculations for smooth drivability
• Helps maintain fuel economy, performance and emissions control
• Built to meet or match the form, fit and function of the original sensor

A failing air charge temperature sensor can cause symptoms such as a check engine light, rough idle, poor fuel economy, hesitation or hard starting. Replacing it with a quality GPD sensor helps restore proper engine management and reliable operation.
