Hella 009409291 Exhaust Pressure Sensor

The Hella 009409291 is a direct replacement exhaust pressure sensor designed for select Hyundai, Kia, and Nissan vehicles. This OEM-quality sensor monitors exhaust back pressure in the diesel particulate filter (DPF) system, providing critical data to the engine control unit for proper emissions control and regeneration cycles.

Key Features:

• Precision exhaust pressure monitoring for DPF systems
• Direct OEM replacement sensor ensuring proper fit and function
• Designed to meet or exceed original equipment specifications
• Durable construction for reliable performance in harsh exhaust environments
• Essential component for maintaining proper emissions compliance

This differential pressure sensor measures the pressure difference across the diesel particulate filter to determine when regeneration is needed. A faulty exhaust pressure sensor can trigger check engine lights, cause DPF regeneration issues, and lead to reduced engine performance. The Hella 009409291 restores proper exhaust system monitoring and ensures your vehicle's emissions control system functions correctly.
