Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Intake Air Temperature Sensor: Description
The Intake Air Temperature (IAT) Sensor (1,6,2) is integrated into the Mass Air Flow (MAF) Sensor. The IAT cannot be serviced separately. Refer to the MAF service procedures for removal. (Refer to FUEL SYSTEM/FUEL INJECTION/MANIFOLD AIR FLOW (MAF) SENSOR - REMOVAL).
The IAT senses the inlet air temperature to the engine. The IAT then sends a signal to the Powertrain Control Module.
