An Intake Air Temperature sensor measures the temperature of the air entering the engine's intake manifold. This data is sent to the vehicle's computer (ECU) to help calculate the correct air-fuel mixture for optimal engine performance and emissions.
Common signs include a check engine light with specific IAT sensor codes (P0110-P0114), rough idling, poor acceleration, decreased fuel efficiency, or difficulty starting the engine, especially in varying weather conditions.
No, this sensor is designed for specific Mercedes-Benz and Chrysler models. You must verify fitment for your exact vehicle before purchasing.
NTC stands for Negative Temperature Coefficient. This means the sensor's electrical resistance decreases as the temperature increases.
OE-quality means the part is manufactured to meet or exceed the standards set by the original equipment manufacturer (the company that originally made the part for the car). This ensures reliability and compatibility.
It is usually found in the intake manifold or the air intake ducting, often near the throttle body or mass airflow sensor.
In most cases, the vehicle's ECU will recognize the new sensor automatically. However, it is good practice to clear any stored trouble codes using an OBD-II scanner after installation.
This could indicate a faulty IAT sensor. Scan the vehicle's OBD-II system for codes related to intake air temperature. If code P0110-P0114 appears, replacement may be necessary.
An inaccurate air temperature reading can affect idle stability. Ensure the sensor is correctly installed and the electrical connection is secure. If the issue persists, the sensor may need replacement.
Incorrect air temperature data can lead the ECU to over-fuel the engine. Verify the sensor is functioning correctly and that other engine components (like O2 sensors and mass airflow sensor) are also in good condition.
If the electrical connector is broken or corroded, it may need to be replaced separately. Ensure any replacement connector is compatible and properly wired.
Compatibility Verification: Before installation, it is essential to confirm that this sensor is compatible with your specific vehicle's make, model, and year. Cross-reference the part number (6PT 009 109-291) with your vehicle's service manual or consult a parts specialist. OEM cross-references include CHRYSLER: 05149209AA, 4862635AA, 5080343AA, 5174042AA, 5174042AB, 5174042AC and MERCEDES-BENZ: 0005422818, 0061532028.
Installation: This sensor is typically located in the intake manifold or air intake ducting. Installation usually involves disconnecting the electrical connector, removing any retaining clips or bolts, and carefully extracting the old sensor. Install the new Hella sensor, ensuring it is securely seated, and reconnect the electrical connector. It is recommended to consult your vehicle's service manual for specific installation procedures or seek professional assistance if you are not experienced with automotive repairs.
Care: Intake air temperature sensors require minimal maintenance. Ensure the electrical connector is clean and free of corrosion. Avoid spraying cleaning agents directly onto the sensor or its connector. If the sensor is located near the air filter, ensure the air filter is clean and properly seated to prevent debris from affecting the sensor.
