The TOPRAN 110 575 Intake Air Temperature (IAT) sensor plays a crucial role in your vehicle's engine management system. It accurately measures the temperature of the air being drawn into the engine. This data is vital for the Engine Control Unit (ECU) to calculate the correct air-fuel ratio. By knowing the air temperature, the ECU can adjust ignition timing and fuel injection for optimal combustion efficiency and power output. A malfunctioning IAT sensor can lead to various drivability issues, including poor fuel economy, rough idling, hesitation, and increased emissions. Replacing a faulty sensor with a reliable component like the TOPRAN 110 575 helps restore proper engine function.
