DPF-R will do the trick used one for about 8000 miles with no problem. Naturally, a small pressure drop is always expected even on new DPFs, due to the fact that the exhaust gases are foreced to flow through the DPF walls. Typically, the engine operating conditions generate high temperatures and allow the passive regeneration of the DPF (self-cleaning). You can buy metal T-pins from hardware stores or online. What is a DPF pressure sensor? Share this: Twitter Follow along with this simple testing method. At ambient temperature25C (77F) and below: Voltage reading should be between 0.61 and 0.77 Volts.

Keep your vehicle turned off while youre plugging in the pins so you dont risk getting shocked. To find which wires are being used for each signal in your car, consult the manual. In this manner, the sensor is able to determine the pressure difference across the DPF, which serves as the primary input data the PCM uses to determine the soot load, and therefore, the efficiency of the DPF. VerticalScope Inc., 111 Peter Street, Suite 600, Toronto, Ontario, M5V 2H1, Canada. You get a considerable pressure drop (offset) with a high flow in a restricted passage, while it tends towards zero with a smaller flow. Just in case anyone's searching for the values, MES is showing the following:-. The Engine Control Module (ECM) uses the Exhaust Pressure Sensor to monitor the pressure differential through the aftertreatment Diesel Particulate Filter. Some posts may contain affiliate links. Categories . I'm in a similar position, my van keeps throwing the p242f code and sending the vehicle into LHM. Not if you can take control of the regen fuel map, it's there just have to find it, I can adjust it on engineering level insite on off road engines, can adjust the fueling value and the timing from almost less than a trickle to 2000* EGT temps.. now you're thinking! If the sensor doesnt work properly, it could make your check engine light come on and cause the engine to hesitate or stumble. Can anyone advise on what the typical DPF Sensor readings in mbar would be in the following situations..? 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 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. If they are found to be damaged or plugged, replace or repair as necessary. GiU#5.R ^1Vq7W~w:5|g*?,LUUsiB,}c" 6#va\lg? They should not be damaged or plugged. 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.

Adding another set of data-points from a 2007 3500 with recent recurring, key-cycle resettable LHM issues and a 2626-1 DTC as shown on my new MD802 scanner: Exhaust Back Pressure at idle - 1517 hPa. Keep your vehicle turned off while you remove the pressure sensor. Remove When this happens it creates all kinds of problems for the truck operator and the fleet. One sensor that keeps an Eagle Eye on the condition of the DPF is the Differential Pressure Sensor.How can we test this sensor and how can we be sure that the ECU is processing what it sees? If the soot load on the DPF is high, the ECM will activate the DPF system warning lamp on the dashboard. The whole system must work in close-knit harmony to deliver a reliable drive, time and again. If you've checked both of the above, then it's time to remove that DPF filter and have it cleaned and checked.

When diesel particulate matter blocks one or both of these airways to the sensor, the sensor can no longer accurately determine pressure changes, which can result in catastrophic damage to the DPF and ultimately the engine. That's the point behind controlling the map designated for the post injection responsible for the added heat and fuel for regeneration. How does a DPF pressure sensor work? DPF SENSOR !!!!!!!! We proudly carry Redline Emissions Products differential pressure sensors for many makes and models, and our parts meet or exceed OEM parameters. 4.6 V depending on differential pressure. I just watched an active regen on my 2007 2500. I've got a long experience as technical trainer and training course developer.

Intake throttle actuator faults: 175, 176, 177, 3539, 3541, 3542, 5879, 5881, 5882 Finally, if youre looking to save money over OEM prices, consider an aftermarket DPF pressure sensor from a company based in North America. Be careful in removing the sensor and hoses, as there are other sensors in this area that can be easily damaged. DPF Technical Information (I) engine management, it is nearly impossible to reach this temperature driving only for a short time. 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. 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 By clicking on them and completing a transaction on the merchants website, I earn a small commission at no extra cost to you.
