Diesel Particulate Filter Pressure Sensor Location

The more the filter is clogged the higher the voltage in volts transmitted by the sensor to the ecu.

Diesel particulate filter pressure sensor location.

However the dpf does not retain small particles and maintenance free dpfs break larger particles into smaller ones. Uses microwaves to detect soot uild up. What does that mean. 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.

Work by estimating soot depending on the increase in the filter pressure drop. 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. In this video we look at a common diesel particulate filter related fault which is highlighting the failure of the differential pressure sensor hoses. What does that mean.

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. Although generic the specific repair steps may vary depending on make model. 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. This gives better power output and lowers exhaust gas emissions.

Although generic the specific repair steps may vary depending on make model. What does code p2453 mean. Detects dpf failure by measuring a change of electrical properties of an. At a specific voltage corresponding to the.

Citation needed there are a variety of diesel particulate filter technologies on the market. This sensor often fails and then the car mistakenly reports the dpf filter as being full. High pressure fuel injection system and variable geometry turbochargers ensure optimal combustion. We recommend torque pro.

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 a circuit. 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. 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.
