Welcome Message from 1A Auto

This replacement Intake Air Temperature Sensor (IAT) or Manifold Air Temperature Sensor (MAT) is a new aftermarket part. It is just what you need to get your vehicle in good running condition again!

How this part works is that it uses a thermistor to control the signal voltage to the vehicles ECM or main computer. The variable resistor changes its resistance based on the intake air temperature. Low intake air temperature produces high resistance, while high temperature causes low resistance. The ECM supplies a constant electrical signal to the IAT sensor through a resistor in the ECM and monitors the voltage change. By monitoring the voltage, the ECM calculates the air temperature and uses this data to assist in determining fuel delivery and spark advance.

A bad or malfunctioning air intake or manifold temperature sensor will often cause a service engine light error code, and or cause a no start condition, or rough running due to inaccurate ignition and fuel timing.

This air intake temperature sensor features:

  • Mounts in the intake manifold or air tube housing
  • Replaces dealer part numbers: 25036751
  • Direct replacement
  • Built to strict quality control standards
  • 100% factory tested
