Detailed Description

This Walker 273-10076 EGT sensor is used in exhaust aftertreatment systems to monitor exhaust temperature before or after the catalyst, particulate filter, or diesel oxidation catalyst depending on the vehicle application. It is listed for 2007-2018 Mercedes-Benz diesel models, including 2018 Sprinter 2500, 2018 Sprinter 3500, 2018 Sprinter 3500XD, 2016-2017 GLE300d, 2017 GLS350d, 2015-2017 Sprinter 2500, 2016-2017 Sprinter 3500, 2013-2015 GL350, 2015 ML250, 2014-2015 Sprinter 3500, 2014 Sprinter 2500, 2010-2013 Sprinter 2500, 2010-2013 Sprinter 3500, 2010-2012 GL350, 2010-2012 R350, 2010-2011 ML350, 2009 GL320, 2009 ML320, 2009 R320, and 2007-2008 R320. This part number, 273-10076, is also cross-referenced to Standard Ignition ETS111 and ETS196 for the same application.

What It Helps Address

• Fault codes related to exhaust gas temperature sensor performance
• Incorrect exhaust temperature readings in diesel aftertreatment systems
• Check engine lights tied to EGT sensor circuit faults
• Regeneration and emissions monitoring issues caused by sensor signal loss
• Hard starting or drivability concerns linked to emission control sensor failures

Installation Notes and Tips

Verify the sensor location before ordering, since this part is used in multiple positions such as before catalyst, after catalyst, after particulate filter, and before DOC depending on the vehicle. Confirm connector shape, terminal style, thread diameter, and harness routing against the original sensor on the Mercedes-Benz Sprinter, GL350, or ML350 application. Use the vehicle service information for the exact mounting point and sensor orientation.
