Facet Exhaust Gas Differential Pressure Sensor

The Facet Exhaust Gas Differential Pressure Sensor (also called a DPF differential pressure sensor or exhaust pressure sensor) monitors the pressure difference across the diesel particulate filter (DPF). It sends this data to the engine control unit (ECU) so the system can track filter loading and manage regeneration.

Key Features:

• Measures the pressure difference between the inlet and outlet of the particulate filter
• Gives the engine control unit the signal it needs to judge soot loading and trigger regeneration cycles
• Helps keep emissions control and engine performance working as designed
• Built for the heat, vibration and exhaust conditions found in automotive exhaust systems
• Aftermarket replacement from Facet, a long-established supplier of automotive components

A faulty differential pressure sensor can cause a dashboard warning light, reduced power, limp mode or incorrect DPF regeneration. Replacing it restores accurate pressure readings so the exhaust aftertreatment system can operate correctly. Select the child item that matches your application.
