Global Parts 1812291 Exhaust Gas Temperature (EGT) Sensor

Exhaust Gas Temperature Sensor Overview

Global Parts 1812291 is an exhaust gas temperature (EGT) sensor for diesel emission control systems. It sends accurate temperature data to the ECM so the engine management system can adjust fuel, exhaust, timing, and cooling strategies as needed. This direct replacement sensor is built to OE specifications for the 2009 Mercedes-Benz GL320 and 2009 Mercedes-Benz ML320.

Key Features

• Exhaust Gas Temperature (EGT) sensor for emission control applications
• Direct replacement design for OE-style fit and function
• Blade terminal type with 2-wire, 2-terminal construction
• Oval connector shape with male connector and female terminals
• Supports accurate ECM input for fuel, exhaust, timing, and cooling control
• Fits 2009 Mercedes-Benz GL320, after particulate filter left and right
• Fits 2009 Mercedes-Benz ML320, after particulate filter
• Part number 1812291 for easy identification and ordering

Detailed Description

Global Parts 1812291 is an OE-spec exhaust gas temperature sensor engineered for precise temperature feedback in the exhaust stream. On the 2009 Mercedes-Benz GL320 and 2009 Mercedes-Benz ML320, this sensor is used after the particulate filter to help the ECM monitor exhaust conditions and manage emissions-related engine operation. The blade-style terminals, oval connector, and 2-wire layout match the original sensor configuration for straightforward replacement. Part number 1812291 also cross-references Standard Ignition ETS195 and Walker Products 273-10018 for the same application.

What It Helps Address

• Fault codes related to exhaust gas temperature sensor performance
• Incorrect ECM temperature readings from the exhaust system
• Emission control issues tied to particulate filter monitoring
• Driveability concerns caused by inaccurate exhaust temperature input
• Replacement needs for a worn or failed EGT sensor on Mercedes-Benz GL320 or ML320

Installation Notes and Tips

Verify connector shape, terminal count, and wire count against the original sensor before installation. This part is positioned after the particulate filter on the listed Mercedes-Benz applications, including left and right locations on the GL320 and after particulate filter on the ML320. Confirm the vehicle’s original sensor location and harness style to ensure proper fitment with part number 1812291.

Quality Assurance

Global Parts engine management sensors are built to send accurate information to the ECM and meet OE specifications for direct replacement use. The sensor is intended to restore factory-style signal accuracy in emission control service on the listed Mercedes-Benz applications.
