Purpose and function of the sensor

The presented sensor is responsible for monitoring the temperature of the air drawn into the intake system, which is crucial for the engine control unit to accurately calculate the fuel dose. In high-end vehicles such as the Mercedes CL and S-Class W215/W220 generations, an accurate temperature reading affects:

• stable idle speed in various ambient conditions,
• smooth acceleration without jerking,
• optimal fuel-air mixture combustion,
• maintenance of proper exhaust emission parameters.

As a result, the sensor is an important part of the engine management system, supporting both driving comfort and engine durability.

Technical characteristics and integration with the intake system

The air temperature sensor in this configuration works with the injection system and the engine controller, transmitting an electrical signal corresponding to the current intake air temperature. The design of the component is adapted for installation in the intake system used in Mercedes CL and S-Class models, which ensures:

• correct positioning in the airflow,
• appropriate response speed to temperature changes,
• a stable signal for the control electronics.

As a part from the Air intake and fuel sensors group, this element works with other intake components, such as the mass air flow sensor, intake manifold, or turbocharging system, to create a coherent measurement system.

Product condition and benefits of choosing a used sensor

The offered sensor comes from the used original parts segment, which allows for combining an attractive purchase cost with the preservation of factory operating characteristics. Choosing a verified used component is particularly beneficial in the case of measurement electronics, where the following matters:

• compatibility with the vehicle's electrical installation,
• factory signal parameters,
• matching the engine controller software.

Thanks to this, it is possible to restore the proper operation of the intake system without the need for a costly replacement with a new component, while maintaining the manufacturer's original specifications.

Selection by part numbers and compatibility

Selecting an air temperature sensor for a specific Mercedes CL or S-Class model should be based on part numbers and catalog data to ensure full compatibility with the specific engine version and model year. In practice, this means matching both electrically and mechanically (connector type, mounting method, operating range).
