VEMO Air Charge Temperature Sensor

The VEMO Air Charge Temperature Sensor (also called an intake air temperature sensor, IAT sensor or charge air temperature sensor) measures the temperature of the air entering the engine. It sends that reading to the engine control unit (ECU). The ECU uses the data to fine-tune fuel injection and ignition timing, which helps the engine run efficiently and respond smoothly.

Key Features:

• Replaces the original air temperature sensor to restore accurate intake air readings
• Uses a temperature-sensitive NTC element, so the signal changes predictably as air temperature changes
• Supports correct air-fuel mixture control for good drivability and fuel economy
• Built to meet the specifications of the original equipment
• Part of the VEMO range, which is made by the Vieth & Co. group and focuses on quality aftermarket parts for European and import vehicles

A faulty air charge temperature sensor can cause a check engine light, rough idle, hard starting, poor fuel economy or reduced power. Replacing it helps restore proper engine management. Choose the specific part number for your application from the options listed on this page.
