Diesel Particulate Filter Pressure Sensor Location

Diesel particulate filter pressure sensor a circuit.

Diesel particulate filter pressure sensor location.

Clouds of black smoke on acceleration are a thing of the past as the soot is trapped by diesel particulate filter dpf. This sensor often fails and then the car mistakenly reports the dpf filter as being full. 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. Uses microwaves to detect soot uild up.

What does that mean. What does code p2453 mean. In this video we look at a common diesel particulate filter related fault which is highlighting the failure of the differential pressure sensor hoses. 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.

Depending on the type of sensing technology that the dpf sensor was developed with these sensors may be divided into four main types. 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. Citation needed there are a variety of diesel particulate filter technologies on the market. At a specific voltage corresponding to the.

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. 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. What does that mean.

Detects dpf failure by measuring a change of electrical properties of an. This gives better power output and lowers exhaust gas emissions. Work by estimating soot depending on the increase in the filter pressure drop. Although generic the specific repair steps may vary depending on make model.

The more the filter is clogged the higher the voltage in volts transmitted by the sensor to the ecu. 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. High pressure fuel injection system and variable geometry turbochargers ensure optimal combustion. Although generic the specific repair steps may vary depending on make model.
