This sensor is a fitment-based replacement for Chevrolet Silverado and GMC Sierra heavy-duty applications, including rear-mounted and turbocharger outlet pipe locations. The 1814749 part number is also referenced by 12672666, 12683487, and ES113344 for the same application.

Key Features

• Direct replacement exhaust gas temperature sensor
• OE specification match for engine management use
• Threaded mounting type for secure installation
• Oval female connector with blade terminals
• 1-wire, 2-terminal sensor design

Detailed Description

Global Parts 1814749 is an EGT sensor used to monitor exhaust temperature and relay that information to the ECM. Accurate exhaust temperature input is important for controlling emissions-related engine strategies and protecting related systems from incorrect temperature readings. The sensor uses a threaded mount, an oval female connector, blade terminals, and a 1-wire configuration for the specified applications.

Compatible With Chevrolet Silverado 2500 HD and Silverado 3500 HD applications in 2017-2021 when used at the turbocharger outlet pipe, and 2022 rear applications on Silverado 2500 HD and Silverado 3500 HD. It also fits GMC Sierra 2500 HD and Sierra 3500 HD in 2017-2021 turbocharger outlet pipe applications, plus 2022 rear applications on Sierra 2500 HD and Sierra 3500 HD. Additional fitment includes 2019-2021 Chevrolet Silverado 4500 HD, Silverado 5500 HD, and Silverado 6500 HD rear applications.

The 1814749 part number is a practical OE-style replacement when the original sensor has failed or is no longer providing reliable exhaust temperature data. Global Parts 1814749 is built to meet OE specifications for the listed vehicles.

What It Helps Address
