Mercedes-Benz Mercedes Sprinter 2006-2018 Emissions & Sensors Specifications

The emissions sensors for the 2006-2018 Mercedes Sprinter are designed to be compatible with the vehicle's specific engine types, including the OM642 and OM651 diesel engines. These sensors are crucial for monitoring NOx, O2, and particulate matter levels, ensuring compliance with Euro 4 and Euro 5 emissions standards. They are not interchangeable with sensors from other vehicle models or engine types. Always verify the part numbers and engine specifications before installation.

Regular maintenance for emissions sensors in a Mercedes Sprinter includes periodic inspection for soot buildup, damage, or wear. Cleaning the sensors during routine servicing can prevent performance degradation. Additionally, ensure the vehicle's exhaust system is free of leaks, as these can cause inaccurate sensor readings. Replacement is typically recommended every 100,000 miles or if diagnostic trouble codes (DTCs) indicate sensor failure.

To install or replace emissions sensors, first locate the sensor in the exhaust system, typically near the catalytic converter or diesel particulate filter. Disconnect the electrical connector and use a wrench to remove the old sensor. Apply anti-seize compound to the threads of the new sensor to prevent corrosion. Install the new sensor, reconnect the electrical connector, and clear any fault codes using a diagnostic tool. Ensure the vehicle is cool before starting the process.

If your emissions sensor is malfunctioning, start by checking for diagnostic trouble codes (DTCs) using an OBD-II scanner. Common issues include sensor contamination, wiring damage, or exhaust leaks. Clean the sensor if it’s covered in soot or debris. Inspect the wiring for damage and repair if necessary. If the problem persists, replace the sensor. Always ensure the vehicle’s exhaust system is in good condition.

To optimize emissions sensor performance, use high-quality diesel fuel and adhere to regular maintenance schedules. Avoid short trips that prevent the exhaust system from reaching optimal operating temperatures. Periodically clean the sensors to remove soot and debris. Ensure the vehicle’s software is up to date, as updates can improve sensor accuracy and overall emissions system efficiency.
