Where is the pentium x40 air temperature sensor?
On the intake pipe.
Air temperature sensor (IAT), located on the intake pipe of the engine, can be installed on the intake pipe in front of the throttle or on the intake manifold behind the throttle; It can be installed separately or integrated into an air flow meter or an intake manifold absolute pressure sensor.
The air temperature sensor is used to monitor the air temperature in the engine intake pipe, and convert the air temperature into a voltage signal and send it to the engine control module ECM, and the ECM realizes the following control according to the signal.
