IAT Sensor<\/h2>\n\n\n\n

An intake air temperature (IAT) sensor is a negative coefficient thermistor that provides the powertrain control module with information about the air temperature that enters the engine.<\/p>\n\n\n\n

IAT Sensor<\/strong><\/a> information is crucial for fuel control and spark timing.<\/p>\n\n\n\n

The IAT sensor can be found in the air cleaner housing, inside the mass airflow sensor, or near the intake manifold.<\/p>\n\n\n\n

The IAT sensor is generally regarded as a low-authority sensor. Still, the PCM uses this sensor as a backup in case the engine coolant temperature sensor is rendered inoperative.<\/p>\n\n\n\n
