Bosch 642-905-02-00 Diesel Particulate Filter Differential Pressure Sensor

The Bosch 642-905-02-00 is a genuine OEM pressure sensor designed for the diesel particulate filter system in 2010-2017 Mercedes-Benz vehicles equipped with 2.1L engines. This DPF pressure sensor connects to hoses before and after the exhaust diesel particulate filter to monitor differential pressure.

Key Features:

• Measures pressure differential between two points to determine DPF fill level and trigger regeneration cycles
• Helps ensure reduction of harmful soot emissions and compliance with emissions standards
• Offers increased accuracy and robustness in harsh exhaust gas environments
• Helps detect cracks or other issues with the diesel particulate filter
• Genuine Bosch OEM quality for reliable performance

A faulty DPF pressure sensor can make the vehicle think the particulate filter is full, potentially causing limp mode and reduced power. This sensor improves engine life by signaling when the diesel particulate filter needs regeneration for efficient emissions reductions. Replacing a failed DPF pressure sensor is essential for maintaining proper exhaust system function and preventing false fault codes.
