GPD 1814353 Air Charge Temperature Sensor Direct Fit IAT Replacement

The GPD 1814353 is a direct-fit replacement Air Charge Temperature (ACT) Sensor, also commonly referred to as an Intake Air Temperature (IAT) sensor or Manifold Air Temperature (MAT) sensor. This sensor monitors the temperature of air entering the engine and relays that data to the vehicle's Powertrain Control Module (PCM), which uses it to optimize fuel delivery, ignition timing, and overall engine performance.

Built to meet or exceed original equipment specifications, this GPD replacement sensor restores proper engine management function and is designed for straightforward, direct-fit installation.

Key Features:

• Direct-fit OE replacement for easy installation
• Restores accurate intake air temperature readings to the PCM
• Helps optimize fuel trim, ignition timing, and emissions performance
• Thermistor-based design with resistance that varies precisely with temperature changes
• Built to withstand underhood heat, vibration, and contamination
• Also known as: IAT sensor, MAT sensor, ACT sensor, Charge Temperature Sensor

A faulty air charge temperature sensor can trigger check engine lights, cause rough idling, poor fuel economy, and reduced engine performance. The GPD 1814353 is a reliable aftermarket solution to restore your engine's air temperature monitoring system to proper working order.
