Welcome Message from 1A Auto


This replacement Intake Air Temperature Sensor (IAT) or Manifold Air Temperature Sensor (MAT) with PLUG are new aftermarket parts. They are just what you need to get your vehicle in good running condition again!

How the IAT 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 with connector features:

  • Mounts in the intake manifold or air tube housing
  • Replaces dealer part numbers: 25036751, 12102620
  • Direct replacement
  • Built to strict quality control standards
  • 100% factory tested
  • Connector with pigtail included in case original plug is frayed or broken

These are electrical parts and are all tested before they leave our warehouse. This electrical item is not returnable, it is only eligible for exchange.

1 Year Warranty

This item is backed by a 1 Year Manufacturers Warranty. In the event this item should fail during intended use, we will exchange the part free of charge (excludes shipping charges) for the original purchaser. Please keep your invoice for proof of this warranty.
