Walker Products 210-1207 Air Charge Temperature Sensor

The Walker Products 210-1207 is a direct-fit replacement Air Charge Temperature (ACT) Sensor, also commonly referred to as an Intake Air Temperature (IAT) sensor. This engine management sensor is engineered to restore precise air temperature measurement to your vehicle's fuel delivery system.

Air Charge Temperature Sensors work by measuring the temperature of incoming intake air through changes in electrical resistance, then sending that data signal to the engine control unit (ECU). The ECU uses this input — along with other sensor data — to calculate the optimal air-fuel mixture, ensuring efficient combustion under all operating conditions.

Key Features:

• Direct OEM replacement — engineered to match original fit, form, and function
• Measures intake air temperature via resistance change for accurate ECU input
• Helps the ECU optimize the air-fuel mixture for improved fuel efficiency and reduced emissions
• Supports proper cold-start performance and engine warm-up calibration
• 100% tested for performance and reliable, worry-free operation
• Manufactured to meet or exceed OEM standards and specifications
• ISO 9001 / IATF 16949 certified manufacturing quality

Walker Products has been supplying the automotive aftermarket with fuel system components and engine sensors since 1946, making them one of the largest privately owned manufacturers in the segment. The 210-1207 is backed by Walker's commitment to quality engineering and precise OEM-equivalent performance.
