Hella 009409171 Exhaust Gas Differential Pressure Sensor

Exhaust Gas Differential Pressure Sensor

The HELLA 009409171 exhaust gas differential pressure sensor monitors pressure differences in the exhaust stream to support accurate diesel emissions system operation. With a bolted mounting design and 3-pole electrical connection, it is built for direct replacement use on select Mercedes-Benz and Jeep applications, including Mercedes-Benz Sprinter 2500 and Sprinter 3500 models.

HELLA product line components are engineered for precise signal measurement in exhaust aftertreatment systems. This sensor is positioned before the soot particulate filter on listed vehicles, making it a key input for DPF-related control strategies on applications such as Mercedes-Benz ML350, R350, and Jeep Grand Cherokee.

• Exhaust gas differential pressure sensor for diesel exhaust monitoring
• Bolted mounting type for secure installation
• 3-pole electrical connection
• Location in exhaust system: before soot particulate filter on listed applications
• Fits select Mercedes-Benz and Jeep diesel models
