Dorman Diesel Particulate Filter Differential Pressure Sensor

The Dorman Diesel Particulate Filter (DPF) Differential Pressure Sensor, also called an exhaust gas differential pressure sensor or DPF pressure sensor, monitors the pressure difference across the diesel particulate filter. It sends that data to the engine control module (ECM). The ECM uses it to judge how much soot has built up in the filter and to decide when to run a regeneration cycle.

Key Features:

• Measures exhaust pressure before and after the diesel particulate filter
• Gives the ECM the signal it needs to manage DPF regeneration and emissions control
• Designed to replace a failed or out-of-range original sensor
• Helps restore normal engine performance and fuel efficiency
• Can help clear DPF-related warning lights and fault codes caused by a faulty sensor

Why Replace It: A failing differential pressure sensor can cause a DPF warning light, reduced power, limp mode, incorrect or frequent regeneration cycles, or a failed emissions test. Replacing it restores accurate exhaust pressure monitoring so the emissions system can work as intended.
