Mercedes-Benz Mercedes S-Class 2005-2013 Emissions & Sensors Specifications

The emissions sensors are designed to be compatible with all 2005-2013 Mercedes S-Class models, including the S350, S500, S600, and S65 AMG variants. These sensors meet OEM specifications and are calibrated to work seamlessly with the vehicle's onboard diagnostics (OBD) system. Ensure the sensor part number matches your vehicle's requirements for optimal performance.

Emissions sensors in the 2005-2013 Mercedes S-Class require periodic inspection to ensure proper functionality. Check for contamination or damage during routine maintenance every 10,000 miles. Cleaning the sensor with a specialized cleaner can prevent buildup. Replace the sensor if error codes related to emissions are detected or if it fails to meet performance standards.

To install or replace the emissions sensor, first, locate the sensor on the exhaust system. Disconnect the electrical connector and use a wrench to remove the old sensor. Apply anti-seize compound to the threads of the new sensor, then carefully thread it into place. Reconnect the electrical connector and clear any error codes using an OBD scanner.

If the emissions sensor triggers a warning light, use an OBD scanner to retrieve the error code. Common issues include sensor contamination, wiring damage, or sensor failure. Inspect the sensor for dirt or damage, clean it if necessary, and check the wiring for faults. If the problem persists, replace the sensor and reset the system.

To optimize emissions sensor performance, ensure the engine is properly tuned and the fuel system is clean. Use high-quality fuel and avoid short trips that prevent the sensor from reaching optimal operating temperature. Regularly inspect the sensor and replace it if it shows signs of wear or malfunction. Keeping the exhaust system in good condition also enhances sensor efficiency.
