Hella 009409511 Exhaust Gas Differential Pressure Sensor 3-Pin Screw Mount

The Hella 009409511 Exhaust Gas Differential Pressure Sensor is a precision-engineered replacement sensor designed to accurately monitor pressure levels within your vehicle's exhaust system. This sensor measures the pressure difference across the Diesel Particulate Filter (DPF) and feeds critical data to the engine control unit (ECU), enabling optimized fuel injection, exhaust treatment, and emissions management.

By maintaining accurate exhaust pressure readings, this sensor helps support Exhaust Gas Recirculation (EGR) system operation and ensures the DPF regeneration cycle functions correctly — keeping your engine running cleanly and efficiently.

Key Features:

• 3-Pin Connector — standard electrical connection for direct, reliable OEM-style integration
• Screw Connection Mounting — secure bolted installation for vibration-resistant, long-term performance
• Without Connecting Pipe — sensor only; no additional pipe included
• Durable Construction — built to withstand extreme exhaust temperatures, vibration, and corrosive gases
• Precision Measurement — delivers accurate differential pressure readings to the ECU for proper engine and emissions management
• Emissions Compliance — supports reduction of harmful exhaust emissions including CO2
• OE-Quality Standards — manufactured by Hella, a globally recognized OEM and aftermarket supplier with over 100 years of automotive expertise

A failing exhaust gas differential pressure sensor can trigger a Check Engine Light (CEL), cause poor fuel economy, increased emissions, sluggish acceleration, or a failed emissions test. Replacing the sensor with a quality Hella unit restores accurate pressure monitoring and proper engine management. Hella part number 009409511.
