Diesel Particulate Filter Pressure Sensor Location

We recommend torque pro.

Diesel particulate filter pressure sensor location.

The pressure sensor measures the difference in pressure between the inlet and the outlet of the dpf the difference in pressure corresponding to the degree of saturation inside the filter. In this video we look at a common diesel particulate filter related fault which is highlighting the failure of the differential pressure sensor hoses. This sensor often fails and then the car mistakenly reports the dpf filter as being full. The more the filter is clogged the higher the voltage in volts transmitted by the sensor to the ecu.

At a specific voltage corresponding to the. Clouds of black smoke on acceleration are a thing of the past as the soot is trapped by diesel particulate filter dpf. Work by estimating soot depending on the increase in the filter pressure drop. Diesel particulate filter pressure sensor a circuit.

Although generic the specific repair steps may vary depending on make model. Uses microwaves to detect soot uild up. This gives better power output and lowers exhaust gas emissions. What does that mean.

High pressure fuel injection system and variable geometry turbochargers ensure optimal combustion. My 2010 audi threw a fit and started complaining about having some issues with error codes about the g450 sensor p0473 exhaust pressure sensor 1 and p245. However the dpf does not retain small particles and maintenance free dpfs break larger particles into smaller ones. Depending on the type of sensing technology that the dpf sensor was developed with these sensors may be divided into four main types.

What does code p2453 mean. Obd ii fault code p2453 is a generic code that is defined as diesel particulate filter pressure sensor a circuit range performance and is set on diesel vehicle when the pcm powertrain control module detects an abnormal voltage in the control and or signal circuit s of the diesel particulate filter pressure sensor that is. Unlike a catalytic converter which is a flow through device a dpf retains bigger exhaust gas particles by forcing the gas to flow through the filter. Diesel particulate filter pressure sensor a circuit low.

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. Citation needed there are a variety of diesel particulate filter technologies on the market. Although generic the specific repair steps may vary depending on make model. This is a guide explaining how to replace the dpf exhaust pressure sensor on the om651 engine which is the engine fitted to the c220 c250 e220 and e250 mercedes cars plus the sprinter and vito vans.
