Bosch Dpf Exhaust Pressure Sensor Diesel Particulate Filter Map The functional principle behind the particulate matter sensor is based on resistance measurement. soot particles are deposited on an electrode structure and form conductive soot trails between the electrodes. prior to each measurement phase, the sensor element is regenerated through heating so that the sensor element adopts a defined status. Top dpf pressure sensor symptoms: increased fuel consumption. excessively high engine & transmission temperatures. an increase in black exhaust smoke. difficulty starting the engine. check engine light. when the sensor has failed, the dpf is expected to follow. if the exhaust gases are unable to pass through the filter, the back pressure will.
Bosch Dpf Exhaust Pressure Sensor Diesel Particulate Filter Map On volvo trucks, spn 3936 often points to a faulty dpf differential pressure sensor. for some cummins engines, this code may suggest an issue with dpf efficiency or soot overloading. the dpf is a critical emissions control device that captures soot from the engine exhaust. it uses pressure sensors to monitor the filter status. The dpf sensor is easy to find, and you can use one of these methods: 1. follow the pressure lines. the pressure lines are a quick and straightforward way to locate the sensor. these will direct you to the sensor. you will find the sensor at the end of the pressure lines on most gl cars. The dpf differential pressure sensor is usually mounted in the engine compartment to protect it from heat. the sensor is connected to the engine control unit (ecu) by an electrical connector and connected to the dpf via two silicon hoses. one hose connects before (upstream) the dpf, the other connects after (downstream) the filter.

The ecm determines the load condition of the dpf based upon the exhaust gas pressure upstream and downstream of the dpc dpf. a pressure differential sensor provides the pressure input to the ecm. during the regeneration process, the ecm raises the temperature in the doc dpf to burn off the soot accumulated.
