Detailed Description

Hella 009409431 is an exhaust gas differential pressure sensor that reads pressure changes in the exhaust stream and sends that information to the vehicle’s control system. That signal is used in EGR-related emissions management, helping the system monitor exhaust flow conditions more accurately. The sensor’s bolted design and 3-pin configuration match the listed Ford and Mercury applications, including 2001-2005 Ford Explorer Sport Trac, 2003-2004 Ford Expedition, 2001-2004 Ford Mustang, 2002-2003 Ford Explorer, 2001-2003 Ford Explorer Sport, and 2002-2003 Mercury Mountaineer.

This part cross-references Ford 4U7E9J460AA and 4U7Z9J460AA for the same application.

What This Sensor Helps Address

• Incorrect exhaust pressure readings in the EGR system
• Emissions control faults related to differential pressure monitoring
• Check engine lights tied to exhaust pressure sensor performance
• Driveability issues caused by inaccurate exhaust flow data
• Fitment problems when replacing a worn 3-pin bolted sensor

Installation Notes and Tips

Assy/Disassy by Qualified Personnel Required. Verify the connector style, mounting type, and vehicle application before installation. For best results, confirm the part number 009409431 against the original sensor and inspect the exhaust system connection points for corrosion or damage before fitting.

Quality Assurance

Hella uses corrosion-resistant materials and durable construction in this sensor to support reliable operation over time. Precise fitment helps maintain sensor accuracy on the listed Ford Explorer Sport Trac, Expedition, Mustang, Explorer, Explorer Sport, and Mercury Mountaineer applications.
