Dorman 926-543 Fuel Temperature Sensor

Dorman 926-543 Fuel Temperature Sensor

Dorman 926-543 is a fuel temperature sensor for select Chevrolet, GMC, and Ford diesel applications. It measures fuel temperature and sends that data to the engine control unit so the system can maintain the proper air-to-fuel mix.

When the original sensor fails, drivability and emissions concerns can follow. This replacement is built to match original equipment performance on specified vehicles, including Chevrolet Express 2500, Chevrolet Silverado 2500 HD, Ford F-250 Super Duty, and GMC Sierra 3500 HD applications.

Key Features

• Direct replacement fuel temperature sensor for specified diesel vehicles
• Measures fuel temperature and relays the signal to the ECU
• Engineered to match original equipment performance
• Oval female connector with 2 terminals
• Operating temperature range: -40 to 150
• Threaded end diameter: 12
• Cross-reference part numbers include Standard Ignition FTS110 and DFT200

Detailed Description

This Dorman fuel temperature sensor is designed for accurate fuel temperature monitoring in 2010-2016 Chevrolet Express 2500 and Express 3500, 2011-2016 Chevrolet Silverado 2500 HD and Silverado 3500 HD, 2011-2016 Ford F-250 Super Duty and F-350 Super Duty, and 2010-2016 GMC Savana 2500 and Savana 3500, plus 2011-2016 GMC Sierra 2500 HD and Sierra 3500 HD.
