Be careful in removing the sensor and hoses, as there are other sensors in this area that can be easily damaged. In theory, theory and practice are the same. We will create 2 new fault codes related to the DPF differential pressure sensor to check if the ECM detects the new conditions. "I started off looking how to test the pressure sensor. i replaced the dpf with a cummins reman. Monitor the temperature readings of the following sensors: The MAXIMUM difference between the sensor readings should be 24oC (43oF). Active and stationary regeneration of the DPF will be disabled. Drawback of Mean Value Pressure Drop Approach - Particulate Micro- . Otherwise issues like you describe will occur. Product Benefits: Quality Control Cost Effectiveness High System Accuracy .

Proceed to check the condition of the ports on the EGR mass mesurement flow assembly. 2 0 obj Will be replacing the Y-cable tomorrow, then re-testing. Poor engine performance; Poor . Below we've included a step-by-step guide to help: If you see that your voltage is off or there are huge differences in pressure values, then it could be time for a new DPF sensor. It does not store any personal data. The DPF differential pressure sensor (DPS) has two pressure sample lines.

Run the engine on high idle without load (around 1600 rpm) for about 10 minutes to warm up the aftertreatment. Thanks, Mike , but I'm trying to figure a way of rodding and chemicaly cleaning it . However at higher rpm and load, things start to get crowded and that's where you'll see a difference. 4.6 V depending on differential pressure. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. P r e p a r a t o r y S t e p s WA R N I N G Batteries can emit explosive gases. If this happens, the DPF can become contaminated and eventually fail. Genuine Cummins 4358939 EGR Differential Pressure Sensor ISX12 and ISX15 Some of the add-ons on this site are powered by. DPFE Sensor Symptoms, Function And Replacement Cost - Mechanic Base If the sensor doesnt work properly, it could make your check engine light come on and cause the engine to hesitate or stumble. P2453 - Diesel Particulate Filter Pressure Sensor "A" Circuit Range If I understand it correctly, this value is a discrepancy in the readings between the two sides of the sensor that the ECU learns and compensates for. w4wn said: You need to leave the pressure sensor module connected to the wiring harness. At ambient temperature25C (77F) and below: Voltage reading should be between 0.61 and 0.77 Volts. The DPF's differential pressure sensor reads a specific pressure that must be programmed into your ECU. The voltage should read a value between the pressure values of both hoses. Monitor DOC inlet pressure sensor voltage pin 87. i also removed the hydrocarbon doser and cleaned that, along with cleaning the imap sensor, cleaning the egr differential ports and sensor, the exhaust back pressure sensor, and even replaced the exhaust pressure . endobj This prevents the valve from malfunctioning and allowing too much exhaust into the intake manifold at one time. The sensor is connected to two hoses one upstream and one downstream from the diesel particulate filter. Thanks to all authors for creating a page that has been read 45,868 times. .

Sensors | Cummins Inc. Share this: Twitter If the DPF has already been replaced during the repair (eg. VerticalScope Inc., 111 Peter Street, Suite 600, Toronto, Ontario, M5V 2H1, Canada. 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. Max differential pressure for G450 ? | Ross-Tech Forums Engine problems: If the engine has malfunctioned, it is possible that excessive soot is created, causing the DPF to get blocked. )FLEET AND SHOP OWNERS - CONTACT US TO SET UP AN ACCOUNT WITH US FOR YOUR DPF CLEANING NEEDS Address: 1120 High Ave SW Canton, Ohio 44707 Phone: 330-573-5396 (for appointment \u0026 parts order only) Email: foxtruckandtractorllc@gmail.comConnect with me on Social Media Platforms: YouTube: http://bit.ly/35YO3kN Repair Business: https://bit.ly/3IELcQJ Instagram: http://bit.ly/3C7hRy6 TikTok: https://bit.ly/3QxGHMT Facebook Page: http://bit.ly/2QqBuZ0 Trucking Facebook Group: https://bit.ly/34TbQXQMy Favoriate Products for trucking \u0026 truck repair needs from Amazon: https://amzn.to/3xZkDn3Awesome Products and Services I Recommend: OTR performance diagnostic tool (super easy scan tool every trucker needs) - use promo code road3333 to get $100 off: https://bit.ly/3O3wshT Rig app (connects mechanics and truck drivers nationwide) Download the Rig app today: https://bit.ly/3B7Cbi2Motive offers the #1 ELDs and Dashcams for the trucking businesses. It's important to rev the engine and check for voltage changes before testing anything else. I have a spare sensor I can send to you, you could install it as a test to eliminate your "new" one..? JavaScript is disabled. Engines that operate longer periods on light loads (eg. Have 3 litre fiat and as self servicing will need multiecuscan. If that doesn't work take it to a garage where they can force a regen using their equipment.. Hi.. well i couldnt find any examples on the of dpf traces on the current scope software. but there was a link to frank massey testing a dpf so hopefully that will give you some answers..if the link works, Fitted the replacement, second hand Sensor this morning, cleared the error codes and executed the "New DPF Sensor fitted" process to reset the ECU.

In other words the higher the differential the faster it goes up the scale. Typically, the ground port is the leftmost or rightmost prong but it may vary depending on the sensor you have. % $159.59. 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. I would think if it was not burnt and had good contacts it should be just fine but instead so many guys just change it out ! TruckPartsAlley(dot)Com at Bonanza - Parts & Accessories, Car The DPF differential pressure sensor is a different sensor that is necessary for filtration to function effectively. Since half of the channels are plugged at the front of the DPF and the other half are plugged at the back of the filter, only half of the filter channels accumulate soot or ash. Does anyone know what "normal" reading should be? For a better experience, please enable JavaScript in your browser before proceeding. Diesel DPF Problems Solved - DPF Differential Pressure - what's If not, check the wiring harness for continuity and correct resistance (less than 10 Ohms). Operating conditions: The engine spends too much time on light load conditions, causing insufficient DPF temperatures which prevent passive regeneration to take place. If the signal is indeed out of specifications, replace the sensor. Figure 1 is a schematic of this sampling apparatus.
