The intake air temperature sensor measures the temperature of the air entering the engine and sends this information to the engine control unit. This helps the ECU adjust fuel mixture and ignition timing to optimize engine performance. Additionally, it also helps with cold start and hot weather performance.

The intake air temperature sensor is an important component in a car's fuel injection system. It detects the temperature of the air entering the engine and adjusts the amount of fuel injected accordingly. This ensures efficient combustion and improves engine performance and fuel economy.
