The BOSCH 0261230090 Intake Air Temperature (IAT) Sensor plays a vital role in your vehicle's engine management system. By precisely measuring the temperature of the air drawn into the engine, this sensor provides critical data to the Engine Control Unit (ECU). This data allows the ECU to calculate the air density and adjust the fuel injection and ignition timing accordingly. Accurate IAT readings are essential for maintaining the correct air-fuel ratio, which directly impacts engine efficiency, power output, and emissions control. Ensuring your IAT sensor is functioning correctly is key to preventing issues such as poor fuel economy, rough idling, hesitation, and potential engine damage. This BOSCH sensor is designed to meet stringent quality standards for reliable and long-lasting performance.
