Diesel Particulate Filter Pressure Sensor Location

Diesel particulate filter pressure sensor a circuit.

Diesel particulate filter pressure sensor location.

Although generic the specific repair steps may vary depending on make model. Although generic the specific repair steps may vary depending on make model. 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. Depending on the type of sensing technology that the dpf sensor was developed with these sensors may be divided into four main types.

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. At a specific voltage corresponding to the. What does that mean. We recommend torque pro.

However the dpf does not retain small particles and maintenance free dpfs break larger particles into smaller ones. Diesel particulate filter pressure sensor a circuit low. Uses microwaves to detect soot uild up. 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.

Detects dpf failure by measuring a change of electrical properties of an. Clouds of black smoke on acceleration are a thing of the past as the soot is trapped by diesel particulate filter dpf. High pressure fuel injection system and variable geometry turbochargers ensure optimal combustion. Citation needed there are a variety of diesel particulate filter technologies on the market.

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

What does that mean. This sensor often fails and then the car mistakenly reports the dpf filter as being full. This gives better power output and lowers exhaust gas emissions. 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.
