Engine Air Temperature Sensor IAT Function: Monitors intake air temperature, allowing the ECU to adjust the airfuel mixture for smoother operation and reduced emissions. Durability: Corrosionresistant housing that reliably operates in extreme conditions for longlasting engine monitoring. OEM compatibility: OEM No. 56028364AA. Replacement quality: OEMstyle IAT sensor designed as a direct replacement for the original part, ensuring a proper fit and restoration of factoryspecified performance. Key attributes Function: Directly feeds intake air temperature data to the ECU to optimize engine performance. Compatibility: Direct replacement for the original sensor with the same connector and mounting interface. Material: Corrosionresistant body for durability in challenging environments. Performance: Restores factoryspecified performance and emissions control. Use scenarios Scenario 1: Replacing a failing IAT sensor during scheduled maintenance to restore smooth idle, responsive throttle, and proper fuel economy. Scenario 2: Installing in vehicles operating in extreme temperatures (hot or cold climates) to maintain accurate intake air readings and reliable engine control. Scenario 3: Replacing worn or degraded sensors to preserve OEM performance and emissions compliance after routine service or repairs.
