Global Parts 1812177 Exhaust Gas Temperature (EGT) Sensor

Exhaust Gas Temperature Sensor Overview

Global Parts 1812177 is an exhaust gas temperature (EGT) sensor for diesel emission control systems. It sends accurate temperature data to the ECM so the engine controller can manage fuel delivery, exhaust strategy, timing, and cooling functions with the correct input.

This direct replacement sensor is built to OE specifications and uses a 2-wire, blade-terminal design with an oval female connector and male terminals. It is a fitment-based replacement for select Chevrolet Express 2500, Chevrolet Express 3500, Chevrolet Silverado 2500 HD, Chevrolet Silverado 3500 HD, GMC Savana 2500, GMC Savana 3500, GMC Sierra 2500 HD, and GMC Sierra 3500 HD applications.

What It Helps Address

• Faulty exhaust temperature readings sent to the ECM
• Emission control warning lights related to sensor signal issues
• Incorrect fuel, timing, or cooling control caused by bad temperature input
• Driveability problems tied to inaccurate exhaust monitoring
• Replacement needs after sensor wear or electrical failure

Installation Notes and Tips

Verify connector shape, terminal count, and wire quantity before installation. Confirm the sensor location and side on the vehicle, since this application is listed as right-side fitment. Inspect the harness connector and surrounding exhaust components for heat damage, corrosion, or contamination before installing the new sensor.

Quality Assurance

Global Parts engine management sensors are built to provide accurate ECM input and are manufactured as direct replacement parts that meet OE specifications for the listed applications.
