Thus at idle of 750 rpm, I have 0. 0 km/h Temperature: 893. 4-7 mbar at idle is not a particularly high value - the increase to 200 mbar when accelerating is quite high. MIL light is on with P2459 code. If the signal voltage varies from the pressure values in the hoses, then there is a problem with the DPF differential-pressure sensor. Thus, engine OEMs tend to limit engine backpressure to approximately 1. If pressure readings are normal: then you are done. This pressure should not exceed 100hPa at Idle. Now i have these values at cold engine: Tomorrow i will start a forced dpf regeneration. Using BlueDriver, I have monitored the DPF pressure, cat temp, and RPM. Do it with old Jul 17, 2015 · -High Exhaust Back Pressure readings on tuner-Normal Manifold Pressure readings Troubleshooting:-Start simple, remove the EBP sensor and clean-Clean the EBP tube-Clean connection on exhaust pipe-Reinstall and check EBP readings. 08 bar when revving. It was a hell studalmost broken the 17mm key on it. 2°C Temperature: 241. When you connect the hoses to the sensor, you should see a reading of 0 to 15 PSI. 5 psi (10 kPa). I assume now that the backpressure value is from a sensor upstream near the turbo, and that the DPF pressure reading is after the DPF and added to this upstream sensor to create a before and after delta-pressure. 85 PSI. The code went away, I reset dpf system, ran Regen. Pop open the hood of your vehicle so you can access the engine. Warming it with a lighter arrived to almost 300 ohm Aug 26, 2023 · 2015 Passat 2. If this happens, the DPF can become contaminated and eventually fail.

The code DOES NOT mean that the DPF needs to be replaced immediately. My V70 shows correct readings but sadly not my XC70. Story: Had a message on dash: Drivetrain- possible to carry on jurney, have it checked. press. A rule of thumb is that the engine power will decrease by 1% for every 3-4 kPa increase in engine backpressure. Most of the time it's less than . The pressure readings were 0. 3: with th Jan 10, 2024 · 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. yes what your seeing is the pressure differential across the dpfas too the location of the pressure tube legs for the pressure transmitter I can only comment on my own golf which is a uk model, that takes its readings pre-dpf filter and post dpf filter,on the exhaust Jul 14, 2022 · As far as I can determine, the DPF is original. 9°C (no May 8, 2018 · Today i changed the temperature sensor. These are signs that the DPF sensor is dying, and the DPF may not correctly regenerate. This P/N has been replaced by Bosch P/N 0281 002 710 or VAG P/N 078 906 051 A.

It is mounted on the firewall just behind the turbo. I had previously replaced the sensor with a new one. 2: check hoses to DPF from the sensor for leaks. 65-0. Do Not perform a diesel particulate filter regeneration if it has been performed recently. Could this be a blocked DPF? I took it on a 60 mile run and the content of the DPF did not change. value 13 hPa IDE07747 Particle filter: differential pressure sensor 1 bank 1: offset 2 hPa IDE07748 Particl. Typical unrestricted DPF Idle reading of = 1. At 2910 rpm: exhaust back pressure 1750 hPa (25 psi); DPF differential pressure 43 hPa (0. Codes: DPF filter limited milage remaining Jan 3, 2025 · Locate the exhaust pressure sensor attached to the engine or the firewall. Does anyone know why this could be happening? In this article you will find about how a Diesel Particulate Filter (DPF) differential pressure sensor works, including; why a DPF differential pressure sensor fails, things to look out for and common fault codes. After cat stabilized at 475-500F, the DPF pressure (PSI) is roughly RPM/1000. Oct 29, 2022 · The original fault on mine was the engine management light on and icarsoft saying "The input for differential pressure sensor 1 in the dpf has a malfunction. It's coming up because it sees the RPM increase, knows that the exhaust gas volume is increasing, and yet thinks that the differential pressure across the DPF isn't rising. May 30, 2020 · When driving, I get the P2002 code (particle filter system below efficiency) and live data shows the pressure differential across the DPF to be constantly at 0. 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. sensor 1 bank 1: adaptat. 9 psi). Jan 1, 2022 · What to Look For in a DPF Differential Pressure Sensor That is Failing . 3 Nm Speed: 0. – Improperly routed differential pressure lines—The exhaust differential pressure line should have a continuous downward gradient without any sharp bends or kinks from the sensor to the DPF. Aug 21, 2023 · Strangely got basically zero readings when truck was running or driving, so either when DPF is truly full the sensor reads basically 0 pressure (I would assume it would read too much back pressure) or the sensor is kaput. Thanks in Feb 20, 2024 · If the differential pressure sensor wasn’t working you would know, as it would trigger a DTC or multiple DTC’s. : differential pressur. It seems be showing me 0HPA on Autel and a Sootmass of 26. 41g ; A Soot mass of 99g would require the DPF to be replaced. If your DPF gauge is constantly reading 0%, it’s most likely because you are operating the truck in a manner that is consistent with best practices. Soot level was at 0, I test drove truck and immediately the over limit service filter notice came up. – A skewed or shifted Exhaust Pressure Differential sensor. . Forgot to mention: the "new" sensor at room temperature +25°C gave me almost 215 ohm resistance (0,22kohm). 2 psi). – Leaks or internal restrictions from theExhaust Pressure Differential sensor lines.
