Typically, the engine operating conditions generate high temperatures and allow the passive regeneration of the DPF (self-cleaning). 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. Active and stationary regeneration of the DPF will be disabled. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. The Cummins ECM uses a Differential Pressure sensor to monitor exhaust flow through the filter. When this sensor is not working properly it compromises the regeneration process and will eventually lead to diesel emissions system failure. An exhaust pressure sensor, also known as an EBP or DPF sensor, measures differences between your vehicle's exhaust before and after it passes through a filter. 2022/3500/6.7/68RFE/Crew C/SB/SRW/TRXOFFROAD Decals/Tradesman/4X4/FRTRPLBPR/TOOLBOX/RCHTRK/ 275 MTR's KEVLAR/ 2" leveling kit Front/1" rear/Metal Grid Protec. Next Post . If voltage is NOT between 0.44-0.56 volts replace the DOC inlet pressure sensor. In an analogue way the upper range 4.8V5.0V is also reserved for sensor diagnosis. This cookie is set by GDPR Cookie Consent plugin. Cummins fault code 1922 becomes active when the soot load of the Diesel Particulate Filter (DPF) has exceeded the recommended limits. : WL-D05013. Exhaust Pressure Sensor 3921027401; Previous Post A diesel particulate filter (DPF) differential pressure sensor measures exhaust backpressure and signals when the power-train control module (PCM) should begin a regeneration process to clear the filter of diesel particulate matter (DPM), or soot. If you notice the numbers changing on the multimeter display, then the sensor has electrical resistance, meaning a current can pass through it and it will still work in your vehicle. Important to note: The vehicle or machine manufacturer is responsible to construct the wiring harness and allow the sensor to eventually connect to the ECM. However, it is usually mounted on the aftertreatment assembly with a heat shield to protect it from heat or in the engine compartment again to protect it from the heat generated by the diesel emissions system. Don't know but mine is in limp mode at the moment and I'm told from initial diagnostics that the soot level is 2%. I'm in a similar position, my van keeps throwing the p242f code and sending the vehicle into LHM. I have a spare sensor I can send to you, you could install it as a test to eliminate your "new" one..? Piss!!!!!!! If you have any of the following fault codes active, troubleshoot them first: Related to aftertreatment regeneration: 2777, 4213, 6416 Variation: If you have trouble keeping the probes against the pins, opt to use ones that have alligator clips and attach them to the pins so you dont have to hold them in place.

Diesel Oxidation Catalyst (DOC) faults: 3313, 3314, 3315, Faults that could be causing excessive soot generation, Fuel System faults: 559, 1139, 1141, 1142, 1143, 1144, 1145, ,4713 If the difference exceeds 24oC (43oF), replace the temperature sensor module assembly (the 3 temperature sensors are connected on the same CAN-BUS module and cannot be replaced separately, or be repaired. Run the engine on high idle without load (around 1600 rpm) for about 10 minutes to warm up the aftertreatment. 3 0 obj wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. Fault codes 1881 and 3134 should become active. Baking that style of filter isn't always a sure thing because of the way it's build.

As I increase rpm to 2000 rpm (parked), back pressure increases to approximately 2000 hpa, and differential . Hunter holds a BFA in Entertainment Design from the University of Wisconsin - Stout and a Minor in English Writing. Once you remove the guts from the DPF, you will end up with a check engine light and the engine will eventually go into De-Rate. These diagnostic trouble code refer to the condition of the exhaust gas Product Introduction. Include your email address to get a message when this question is answered.
