Hella Air Charge Temperature Sensor

The Hella Air Charge Temperature Sensor (also called an intake air temperature sensor, IAT sensor, or manifold air temperature sensor) measures the temperature of the air entering the engine. It sends this data to the engine control unit (ECU) so the unit can adjust fuel delivery and ignition timing accurately.

Key Features:

• Monitors intake air temperature to help the ECU keep the air-fuel mixture correct
• Helps support smooth running, good fuel economy, and controlled emissions
• Uses a temperature-sensitive (NTC thermistor) sensing element that sends a signal to the engine control unit
• Designed to meet OE-level fit, form, and function
• Made by Hella, a long-established supplier of automotive electrical and electronic components to vehicle manufacturers

A failing air charge temperature sensor can contribute to symptoms such as rough idle, poor fuel economy, hard starting, or a check engine light. Replacing it with a quality sensor helps restore proper engine management performance.
