How does this sensor affect engine performance?

The IAT sensor provides the engine control unit with precise intake-air temperature data, which is one of the inputs used to calculate fuel delivery and timing. When the ECU receives accurate temperature readings, it can better estimate air density and adjust fueling, improving combustion balance and drivability.

• Delivers real-time temperature readings to the ECU for air–fuel ratio adjustments.
• Helps the ECU correct ignition timing based on intake conditions.
• Supports smoother idle and consistent throttle response by refining fuel trims.
