Hella Intake Air Temperature Sensor - Air Filter Housing

An Intake Air Temperature (IAT) sensor measures the temperature of the air entering the engine's intake manifold. This information is crucial for the engine control unit (ECU) to adjust fuel injection and ignition timing for optimal performance and efficiency.

Automotive manufacturers sometimes use different sensor designs or have variations in components even within the same model year or engine type. Verifying measurements ensures you receive a sensor that physically fits and functions correctly in your specific vehicle.

Common signs include a Check Engine Light (CEL) with IAT-related codes, rough idling, poor acceleration, decreased fuel economy, and difficulty starting the engine, especially in extreme temperatures.

Warranty information can vary. Please refer to the specific retailer's product listing or contact Hella customer support for the most current warranty details applicable to this part number.

Installation is generally straightforward for individuals with basic automotive mechanical knowledge. However, if you are not comfortable with automotive repairs, professional installation is recommended to ensure correct fitment and avoid potential damage.

While both measure air entering the engine, the IAT sensor specifically measures the *temperature* of the air, while the MAF sensor measures the *mass* (or volume and density) of the air. Both are critical for proper engine management.

Please carefully check the compatibility list provided in the product description against your vehicle's exact make, model, year, engine type, and any specific notes regarding measurements. If unsure, consult a professional mechanic or the vehicle manufacturer.

Ensure the sensor is correctly seated and the electrical connector is fully engaged. Clear any existing fault codes using an OBD-II scanner. If the light persists, re-verify compatibility and consider professional diagnosis.

Confirm the sensor was installed correctly and is the exact OE-equivalent part for your vehicle. Check the air intake system for leaks or obstructions. A faulty sensor may need replacement.

A malfunctioning IAT sensor can affect fuel mixture on startup. Double-check the sensor's connection and ensure no other engine performance issues are present.

Ensure the sensor is functioning correctly and is compatible with your vehicle. Other factors like tire pressure, driving habits, and other engine components also affect fuel consumption.
