Dorman 904-7430 Exhaust Backpressure Sensor

Exhaust Backpressure Sensor for OE-Style Replacement

Dorman 904-7430 is an exhaust backpressure sensor built to match the fit and function of the original unit. It helps restore accurate exhaust pressure input to the engine control unit when the factory sensor has failed from heat exposure or internal damage. This OE-style replacement is a practical choice for diesel exhaust backpressure sensor service on vehicles such as Ford F-250 and Ford F-350 applications that rely on precise exhaust system feedback.

Key Features

• Exhaust backpressure sensor for exhaust system diagnostics and ECU input
• OE-style fit and function for direct replacement service
• 4-terminal connector design with round male connector shape
• M12-1.5 thread diameter for the specified application
• Grey/silver sensor housing finish
• Dorman 904-7430 cross-references OE-style part numbers for the same application

Detailed Product Overview

This Dorman exhaust backpressure sensor is designed for vehicles that depend on accurate exhaust pressure readings to manage engine operation. When the original sensor is damaged by heat or internal component failure, the ECU can receive incorrect data, which can affect drivability and emissions-related performance. Dorman 904-7430 is built as a direct replacement sensor with the specified connector style, terminal count, and M12-1.5 thread size for a proper service fit. It is a relevant replacement for diesel exhaust backpressure sensor repair on Ford F-250 and Ford F-350 models where the original sensor has failed.

This part cross-references Monroe Shocks & Struts (e.g., 577.75525OE, 1002-1011) for the same application.

Common Problems This Sensor Can Address

• Faulty exhaust backpressure signal to the engine control unit
• Check engine light related to exhaust pressure sensor failure
• Poor engine response caused by incorrect exhaust pressure data
• Sensor damage from heat exposure in the exhaust system
• Internal sensor component failure affecting diesel exhaust monitoring

Installation Notes and Tips

Verify connector shape, terminal count, and thread diameter before installation. Confirm the sensor location and compare the original part number to Dorman 904-7430 for the correct exhaust backpressure sensor replacement. Clean the mounting area and inspect the harness connector for heat damage or corrosion before connecting the new sensor. For Ford F-250 and Ford F-350 exhaust sensor service, match the original sensor configuration exactly to avoid fitment issues.

Quality Assurance

Dorman designs this sensor to match original fit and function, helping restore proper ECU input after the factory unit has failed from heat or internal damage. Dorman 904-7430 is built for direct replacement use in the specified exhaust sensor application.
