Diesel Particulate Filter Pressure Sensor

This diagnostic trouble code dtc is a generic powertrain code which means that it applies to all 1996 newer vehicles ford dodge gmc chevrolet mercedes vw etc.

Diesel particulate filter pressure sensor.

The ends of the filter plugged in a checkerboard pattern force the soot containing exhaust to flow through the porous filter walls. What does that mean. How much does it cost to replace a diesel particulate filter. Decarbonizing allows to burn the carbon and cleans your engine.

Although generic the specific repair steps may vary depending on make model. Order diesel particulate filter pressure sensor for your vehicle and pick it up in store make your purchase find a store near you and get directions. How to clean your dpf sensor. The signal of the sensor is not sufficient to determine an optimized timing for regeneration of the dpf.

The differential pressure feedback exhaust sensor or dpfe sensor is part of the vehicle s exhaust gas recirculation egr system. Sensors upstream and downstream of the dpf or a differential pressure sensor provide readings that initiate a metered addition of fuel into the exhaust stream. Your order may be eligible for ship to home and shipping is free on all online orders of 35 00. Differential pressure sensor delta p for particulate filter applications the pressure sensor described underneath is mainly used to monitor the soot loading of a particulate filter on a diesel engine or gas turbine.

Replacing a diesel particulate filter can be pricey. Preventive engine cleaning enables you to restore engine parts rather than replacing them thereby saving vehicle owners on costly parts such as a new turbocharger 1 350 3 100 catalytic converter 600 2 000 dpf 600 2 000 or egr valve 370 500. The sensor monitors and measures the pressure with the egr valve. Diesel particulate filter pressure sensor a circuit.

Not all dpf systems have a parked regeneration feature. You ll know if it stops working as you ll see a warning light on your dashboard. This prevents the valve from malfunctioning and allowing too much exhaust into the intake manifold at one time. The most common diesel particulate filters in widespread use are cellular ceramic honeycomb filters with channels that are plugged at alternating ends as shown in figure 1.

The dpf differential pressure sensor detects the difference between the exhaust pressure upstream and downstream of the diesel particulate filter by means of the exhaust pressure sampling pipes upstream and downstream of the dpf. There are two methods to inject fuel either downstream injection directly into the exhaust stream downstream of the turbo or fuel injection into the engine cylinders on the exhaust. A faulty dpf sensor means trouble for your car your chances of getting an mot and making it difficult to sell. A new filter from a car manufacturer can cost anywhere from 3 000 to 10 000.
