Dorman 904-7557 Exhaust Gas Temperature (EGT) Sensor

EGT Sensor Replacement with Bung Repair

Dorman 904-7557 is an exhaust gas temperature (EGT) sensor replacement built for specific applications where the original sensor can seize in the exhaust bung. It includes a bung repair kit for cases where removal damages the mounting point, helping restore the exhaust sensor location without replacing the entire assembly.

Compatible With select diesel exhaust temperature sensor applications, this Dorman OE FIX solution addresses a common service problem with a direct-fit sensor and repair support. Part number 904-7557 is a practical choice for technicians servicing emissions systems on vehicles such as Ford F-250 and Ford F-350 diesel models where EGT sensor service is required.

Key Features

• Exhaust Gas Temperature (EGT) sensor for emission control service
• Specific fit replacement for the original sensor location
• Includes 1 bung repair kit and 1 zip tie in the package
• Straight sensor design with 12 mm thread diameter and 1.25 mm thread pitch
• Gray connector with male connector and terminal ends
• Single-wire harness with 455 mm wiring harness length
• 2-terminal blade-style construction
• Tip width measures 4.8 mm

Detailed Description

Dorman 904-7557 is engineered as a direct replacement EGT sensor for specific diesel exhaust systems. The sensor uses a straight configuration, gray irregular connector, and a single-wire layout with 2 male blade terminals. Its 12 mm thread diameter and 1.25 mm thread pitch support a precise threaded installation in the exhaust bung.

This part is especially relevant when servicing Ford F-250 and Ford F-350 applications that rely on accurate exhaust gas temperature monitoring for emissions control. If the original sensor seizes during removal and damages the bung, the included repair kit provides a path to restore the mounting point. This part cross-references 2593756C91 for the same application.

What It Helps Solve

• Seized EGT sensor removal from the exhaust bung
• Damaged bung threads after sensor extraction
• Faulty exhaust gas temperature readings
• Emission control warning lights related to sensor failure
• Service delays caused by a damaged sensor mounting point

Installation Notes and Tips

Verify the connector style, thread size, and harness length before installation. The sensor is a specific-fit part, so confirm application details against the vehicle’s original EGT sensor configuration. Use care during removal to avoid additional damage to the exhaust bung, and follow the repair kit instructions if the bung threads are compromised.

For Ford F-250 and Ford F-350 diesel service, compare the original connector shape, terminal count, and thread pitch to ensure the replacement matches the factory setup. Part number 904-7557 is intended for direct sensor replacement in the correct application.

Quality Assurance

Dorman OE FIX parts are built to address common failure points with service-focused replacement solutions. This sensor package is supplied as a specific-fit component for the listed application and includes the bung repair kit needed when exhaust bung damage occurs during EGT sensor service.
