Intake Air Temperature (IAT) Sensor

TABLE OF CONTENTS

What is the Intake Air Temperature (IAT) Sensor?

The Intake Air Temperature (IAT) Sensor is used by the engine’s Power Control Module (PCM) to decide at which rate the engine should spark and inject fuel to obtain optimal performance. This is possible because the IAT sensor uses the air density and air temperature in the car’s environment and analyzes it to determine the correct amount of spark and fuel injected. This helps the engine to start up on a cold day and also keeps consistent fuel economy during hot days. The sensor has become more important over the years because of the need for maintaining the correct combustion mixture and emission level. There are multiple types of IAT sensors. Check your car’s service manual to verify the location of your IAT sensor so that you are able to repair if needed.
