Global Parts 1814756 Exhaust Gas Temperature (EGT) Sensor - Exhaust Manifold

Exhaust Gas Temperature Sensor for GM HD Trucks

Global Parts 1814756 is an exhaust gas temperature (EGT) sensor for diesel emission control systems. It sends accurate exhaust temperature data to the ECM so the engine can manage fuel delivery, exhaust strategy, timing, and cooling functions. This direct replacement sensor is built to OE specifications for service on Chevrolet Silverado 2500 HD, Chevrolet Silverado 3500 HD, GMC Sierra 2500 HD, and GMC Sierra 3500 HD applications.

Key Features

• Part type: Exhaust Gas Temperature (EGT) sensor
• Direct replacement design for OE-style service
• Built to send accurate temperature information to the ECM
• Threaded mounting type for exhaust manifold installation
• Female connector with oval shape
• 2-terminal blade connection with 1-wire configuration
• Cross-references Standard Ignition TX350 and OE-style numbers 12675840 and ES113351
• Global Parts 1814756 for diesel emission control repair

Detailed Description

Global Parts 1814756 is an emission control sensor engineered for exhaust manifold mounting on 2017-2021 Chevrolet Silverado 2500 HD, 2017-2021 Chevrolet Silverado 3500 HD, 2017-2021 GMC Sierra 2500 HD, and 2017-2021 GMC Sierra 3500 HD models. The sensor uses a threaded mount, oval female connector, male blade terminals, and a 1-wire layout with 2 terminals to match the original-style electrical interface. By reporting exhaust gas temperature to the ECM, this EGT sensor supports proper control of fuel, exhaust, timing, and cooling systems. If you are replacing a failed Global Parts 1814756 sensor on a Silverado HD or Sierra HD diesel application, this OE-spec replacement is built for direct service fitment.

This part cross-references Standard Ignition TX350 for the same application.

Common Problems This Sensor Can Help Address

• Fault codes related to exhaust gas temperature sensor performance
• Incorrect exhaust temperature readings sent to the ECM
• Emission control system faults on diesel trucks
• Driveability issues tied to inaccurate exhaust temperature data
• Cooling, timing, or fuel strategy concerns caused by sensor failure

Installation Notes and Tips

Install the sensor at the exhaust manifold location specified for the vehicle application. Confirm connector shape, terminal count, and threaded mounting style before installation. Inspect the harness and connector for heat damage, corrosion, or broken terminals, since exhaust sensors often fail alongside wiring issues. Clear diagnostic trouble codes after replacement and verify proper ECM data during a road test.

Quality Assurance

Global Parts engine management sensors are made to provide accurate information to the ECM and meet OE specifications for direct replacement service.
