• Direct replacement design for OE-style fit and function
• Blade terminal type with 2-wire construction
• Oval female connector with 2 terminals
• Built to provide accurate information to the ECM
• Supports engine management systems that monitor exhaust temperature

Detailed Description

Global Parts 1812289 is an EGT sensor used to measure exhaust gas temperature before the catalytic converter on select Mercedes-Benz diesel applications. It is engineered to deliver the temperature signal the ECM relies on for managing emissions-related engine operation. This part fits 2013-2015 Mercedes-Benz GLK250, before catalytic converter, and 2012-2013 Mercedes-Benz S350, before catalytic converter. The Global Parts 1812289 sensor is a direct replacement option for drivers and technicians servicing Mercedes-Benz GLK250 and Mercedes-Benz S350 exhaust temperature faults.

This part cross-references Dorman OE Solutions 904-771 for the same application.

What It Helps Address

• Check engine lights related to exhaust temperature sensor performance
• Incorrect exhaust temperature readings sent to the ECM
• Emission control system faults tied to the EGT circuit
• Driveability issues caused by inaccurate engine management input
• Fault codes affecting fuel, timing, exhaust, or cooling control strategies

Installation Notes and Tips

Install in the original sensor location before the catalytic converter on the listed Mercedes-Benz GLK250 and Mercedes-Benz S350 applications. Verify connector shape, terminal count, and wire configuration against the removed sensor before installation. Clear diagnostic trouble codes after replacement and confirm the ECM receives a stable exhaust temperature signal.

Quality Assurance

Global Parts engine management sensors are built to meet OE specifications and are intended to provide accurate ECM input for emission control service. The 1812289 part number is made as a direct replacement sensor for the listed Mercedes-Benz applications.
