Intake Air Temperature Sensor What is an intake air temperature sensor? An intake air temperature sensor (IAT) can be located in the intake air duct from the air filter box or in the intake manifold to the engine. It’s job is to report the temperature of the outside air being drawn into the engine. The sensor reports its findings directly to the powertrain control module or engine control module. The PCM/ECM uses the intake air temperature reading to calculate how much fuel to add to the incoming air. IAT and … Read More

Fix code P0110 Intake Air Temperature Circuit Malfunction The Intake Air Temperature sensor installs in the air duct from the air filter up to the throttle body. Or, in some makes, it installs in the upper intake manifold. The sensor is a variable resistance sensor that modifies the voltage applied to it based on the temperature of the incoming air. These are usually two-wire sensor with one wire providing a reference voltage and the other wire as ground. The PCM monitors the voltage on the reference wire. To test the … Read More
