Hella 009409391 Exhaust Gas Differential Pressure Sensor

HELLA Exhaust Gas Differential Pressure Sensor

The HELLA Exhaust Gas Differential Pressure Sensor monitors exhaust pressure differences to help maintain accurate EGR operation and emissions control. Built with corrosion-resistant materials and a durable housing, this sensor is made for dependable performance on Ford, Lincoln, and Mercury applications that use a 3-pin, bolted design.

Part number 009409391 is a direct-fit style replacement for a wide range of vehicles, including Ford Ranger, Ford F-150, Ford Explorer, and Mercury Mountaineer applications. If you need an exhaust gas differential pressure sensor for a 3-pin connector and bolted mounting setup, 009409391 is built to match the original configuration.

Detailed Description

HELLA 009409391 is an exhaust gas differential pressure sensor engineered to read pressure changes in the exhaust system and relay that information to the vehicle’s control strategy. Accurate pressure feedback is important for EGR function and emissions management, especially on older Ford, Lincoln, and Mercury trucks, vans, and passenger vehicles that rely on a 3-pin, bolted sensor layout. This part cross-references VEMO V25-72-1223 for the same application.

What It Helps Address

• Faulty exhaust pressure readings that can trigger emissions-related trouble codes
• EGR system performance issues caused by inaccurate differential pressure feedback
• Rough running or drivability concerns tied to incorrect exhaust pressure data
• Sensor failure from corrosion or heat exposure in the exhaust environment
• Fitment problems when replacing a 3-pin, bolted exhaust gas differential pressure sensor

Installation Notes

Assy/Disassy by Qualified Personnel Required. Verify the connector style, mounting type, and sensor dimensions before installation. This HELLA sensor uses a bolted mount and 3-pin connection, so matching the original configuration is important for proper fitment on Ford Ranger, Ford Explorer, Ford F-150, and related applications.

Quality Assurance

HELLA builds this sensor with corrosion-resistant materials and durable construction to support reliable operation in demanding exhaust-system conditions. Precise fitment helps maintain sensor accuracy on the specified Ford, Lincoln, and Mercury vehicles.
