Global Parts 1812287 Exhaust Gas Temperature (EGT) Sensor

Exhaust Gas Temperature Sensor Overview

Global Parts 1812287 is an exhaust gas temperature (EGT) sensor for diesel emission control systems. It sends accurate temperature data to the ECM so the engine can manage fuel delivery, exhaust strategy, timing, and cooling functions with the correct input.

This direct replacement sensor is built to OE specifications and is a fitment match for select Mercedes-Benz GL350, R350, and ML350 applications. If you are replacing a faulty Mercedes-Benz EGT sensor, Global Parts 1812287 provides the correct connector style and terminal layout for the listed vehicles.

Key Features

• Exhaust Gas Temperature (EGT) sensor for emission control systems
• Direct replacement design for OE-style fit and function
• Accurate signal output to the ECM for engine management
• Blade terminal type with 2-wire construction
• Oval connector shape with male connector and female terminals
• Built to meet OE specifications for the listed applications

Detailed Product Information

Global Parts 1812287 is engineered for diesel exhaust monitoring where precise temperature feedback is required. The sensor helps the ECM interpret exhaust heat levels so the vehicle can manage related systems more accurately. This matters on Mercedes-Benz GL350, R350, and ML350 models equipped with particulate filter-related EGT sensor locations, including front-in-filter and before-particulate-filter positions shown in the fitment data. The part number 1812287 is also a useful reference when cross-checking replacement options for the same application.

This part cross-references Standard Ignition ETS190 and Walker Products 273-10121 for the same application.

What This Sensor Helps Address

• Fault codes related to exhaust gas temperature readings
• Incorrect ECM temperature input from a failing EGT sensor
• Diesel particulate filter monitoring issues
• Driveability problems tied to emission control sensor failure
• Reduced engine management accuracy in Mercedes-Benz diesel applications
