The sensor monitors and measures the pressure with the EGR valve. Thank you in advance for your support! The DPF differential pressure sensor plays an important role in keeping the DPF functioning properly. Monitor the temperature readings of the following sensors: The MAXIMUM difference between the sensor readings should be 24oC (43oF). A differential pressure sensor is an electronic sensor that measures back pressure before and after the DPF and determines the level of soot contained within the DPF. whether or not its possible id definitely appreciate any help as i dont know about resistors and would definitely like to try this out was thinking of wiring up something to a set of switches that when flipped it will progressively fool the sensor into thinking the filter is actively cleaning or becoming blocked. for example on a deleted truck that the aftertreatment system hasnt been disabled only codes shut off, the truck will want to go into a timed/forced regen even though there is no DPF. Use a wire to see if the ports are free of soot all the way to allow pressure to reach the sensor. You could also create a free QuickServe Online Account to access all Cummins manuals and wiring diagram for your engine. what im trying to do is to actualy fool the ecm into thinking it is performing a regen successfully when it goes into a timed (forced) regen.

Cummins Dpf Differential Pressure Sensor Reading If you are working in a diesel engine, then you know how important it is for the engine to have a good diesel particulate filter. The differential pressure sensor on a diesel particulate filter (DPF) is used by the ECU to monitor backpressure and determine when regeneration is required to clear DPM or soot from the system. When this sensor is not working properly it compromises the regeneration process and will eventually lead to diesel emissions system failure. So if the front hose reads 1 PSI and the rear hose reads half PSI, the signal wire voltage should read somewhere around .8 volts. If voltage is NOT between 0.44-0.56 volts replace the DOC inlet pressure sensor.

At one point it reports the charge status of the particle filter and monitors its function. Check out my diagnostic tool suggestions! Going to get it on a mates pit at weekend and double check for blockages in the sensor pipes more thoroughly, mine sits at max 14mbar whilst idling which still seems high, possibly. If the air filter is restricted, it could affect the air/fuel ratio causing excessive soot generation. If you've checked both of the above, then it's time to remove that DPF filter and have it cleaned and checked. Ram Cummins with lots-o-mods. To test if your battery is working properly, you'll need to connect the multimeter ground with one lead connected directly onto its negative terminal and run a quick "plausibility" check.
