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. If the air filter is restricted, it could affect the air/fuel ratio causing excessive soot generation. Guys, my MD802 is telling me that the DPF is too clogged to regen so I'm assuming that it can only be cleaned by taking it out and manualy cleaning it , chemical or roding it out ?? Share this: Twitter If you notice the rubber hose has cracks or damage, replace it as soon as you can since it may leak later on. 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. +5 Volt supply, ECM Return, DPF outlet pressure signal, DPF differential pressure signal. What is a DPF pressure sensor? I had a conditional pass but only aloud that one time, now need to fool it or return to stock. Monitor DOC inlet pressure sensor voltage pin 87. Too spendy to have it serviced at MB or Dodge , money I don't have . If you have any of the following fault codes active, troubleshoot them first: Related to aftertreatment regeneration: 2777, 4213, 6416 This image is not<\/b> licensed under the Creative Commons license applied to text content and some other images posted to the wikiHow website.

\u00a9 2023 wikiHow, Inc. All rights reserved. The soot load of the Diesel Particulate Filter is monitored by the DPF differential pressure sensor. If the signal is indeed out of specifications, replace the sensor. Proceed to check the condition of the ports on the EGR mass mesurement flow assembly. The parts tend to make up the majority of the cost, usually between $100 and $400, while the labor might only be $50 to $100. Avoid removing both hoses from the pressure sensor since you wont produce accurate results. My understanding is that the 40420 does not have DPF delete capabilities. 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. You can buy vacuum pumps online or from auto part stores. When this happens it creates all kinds of problems for the truck operator and the fleet.

Turn on the ignition switch without starting the engine. It will need to either be removed, professionally cleaned, or replaced, both options being much more than the cost of diagnosing and replacing a faulty sensor. 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. The differential pressure sensor measures the pressure drop between two points in the flow pattern and is used at two different points in the exhaust manifold. This image is not<\/b> licensed under the Creative Commons license applied to text content and some other images posted to the wikiHow website. When the diesel particulate filter is not regenerating properly due to the faulty DPF sensor failing you may experience some of or all of the below symptoms: A DPF pressure sensor is necessary to keep the DPF free from diesel particulate matter and soot, and if the DPF is plugged, the regeneration process will not fix it.
