Kind of; DPs were reporting negative values. 1st you can not force regen a bmw The exhaust back pressure (EBP) sensor gauges the pressure of the exhaust gasses before and after it passes through the diesel particulate filter (DPF) to see if the pressure has changed. keeps throwing the P2002 code. com Launch UK products used in the video are When reading fuel rail pressure live data on idle the values go up and down sporadically between 27000-30000 kPa (270-300 bar). 89 Differential Pressure Sensor: $63. 530D SE exhaust back pressure sensor, DPF. The differential pressure sensor was reading ~950mbar at any time; ignition on engine off, idle, cruising 2k rpm, and WOT. kierongrant82. 0 Basket; Wishlist. For sufficient accuracy, use an exhaust back pressure gauge that measures 0-15 PSI. The issue is exactly as read: exhaust back pressure sensor. New media Back pressure sensor Location A180 1. 5 grams which is okay in my book as tells us the DPF filter is not blocked. On fitting, they said the dpf was too blocked to regen so they flushed it out. DPF Pressure Sensor: This sensor monitors the exhaust back pressure before it enters the DPF. I mean its negative to that. A diesel particulate filter (DPF) pressure sensor is designed to measure exhaust backpressure and then let the power-train control module (PCM) know when the filter needs to be cleaned by performing regeneration. A clogged DPF will generate another fault code and most likely with a reduced power warning. The DPF ash is fully reduced chemically at very high temperatures, equivalent to very strong chemical reducing agents, the strongest that there are Diagnosing And Replacing A DPF Sensor. They’re collected during low-load conditions. It would be best to have your mechanic with DPF capacity and content are models based on differential pressure. Jump to Latest WID - The DDE (Digital diesel electronics - or engine control unit) has detected a fault with the exhaust back pressure sensor due to faulty pressure readings from this circuit it has set the code Tyre Inflators & Pressure Gauges Speed & Cadence Sensors Fitness Watches Heart Rate Monitors Cycle Computer & GPS Mounts Power Meters All Cycling Technology Fitness & Wellbeing Back Bike Parts Mudguards Bike Brakes - Found that engine harness has been melted and the DPF pressure sensor tube had come off it and walk away. 2009 bmw x5 35d M57N2 engine 132k miles I have a 2013 35D, and I have the code 4D03, pressure sensor reads accurately but differential (DPF) sensor reads negative values and i believe. Do same with pre dpf sensor pipework. That Happily all sorted now. Symptoms of a faulty exhaust back pressure sensor failure in BMW include decreased fuel efficiency, sputtering and stalling engine, an illuminated check engine light, and more emissions. have seen similar readings for exhaust back pressure sensor, given the sensors are still connected. I just bought a new one (Hella) and I replace it (plug and play) but still I Barometric Pressure 14. temp. The Exhaust Back-pressure Sensor Running through DIS I have a new fault code present showing signal too high on the back pressure sensor. 315 psi with cold exhaust engine off about 17. After checking those components, take the vehicle for a test drive with an OBD-II scanner connected to track the back pressure sensor readings. Then they said the exhaust back pressure sensor was faulty, as it was reading about 8bar. Its the same one as in MK 3 focus and Mk 7 Fiesta. Toggle menu. You need to get a scanner and see what codes you have. The first minute the car felt completely different like full power Car fumes are one of the biggest sources of air pollution. of course I change the Another live test and the DPF Pressure sensor reading is moving again. 6 Others may disagree, but I think the preponderance of evidence shows a link between glow plugs and dpf. Pop open the hood of your vehicle so you can access the engine. Tags 525d e60 dpf 525 e60 exhaust back pressure no power. Good luck. Fitted a new sensor and still the same reading. 04hPa (-19mbar), picture in attachment. Hi all great forum. Use Wurth DPF cleaner. This pressure should not exceed 100hPa at Idle. Next job in a few days and several varied journeys, I will again run an OBD scan with fingers crossed for little to no codes. Key Components Involved. 55 roughly once it's complete. This makes me think the Exhaust Back Pressure Sensor is OK because it does read different pressures. strange negative dpf back pressure reading?? Bimmerpost ☰ Model Selection. It's the sensor that measures the pressure across the DPF. 62 mbar Boost pressure actual value: 2333. Bimmerlink also can read DPF status and values - not as extensively as ISTA, but still, enough to assess DPF health. Also I checked the DPF reading and it says Ash Mass was 22 and Soot Mass 49. When I checked yesterday readings with Rheingold (ISTA+), I get on start of engine temp. Jump to Latest 5. F40Model Year: 2019 + Previous Generations 2013 - 2019. Inspect DPF pressure sensor supply hoses for clogs, cracks, or collapse. more specifically confirm DPF regen is happening and DPF is not getting Either your DPF is full or a the pressure sensor isnt working well BMW 318d se auto 2013. Welcome to the BMW Shop. The maximum permitted value on the 330d (for example) is 35mBar. Watch this space. xoutpost. 3. If that increases it goes into a regen cycle As per the URL you attached. It sends a signal to the powertrain control module (PCM) to regulate the DPF regeneration process. xx PSI. This process is carried out by feeding a richer fuel mixture into the engine The mechanic did a DPF clean and forced regen and claimed it was fixed only for the engine light to come back in two days later. 84mbar, charging pressure:1003. Knowing that the dpf could be a problem on diesels I choose under DMe diagnosis the back pressure exhaust reading and was surprised to see -999. freq: 5, healing counter: 30, engine idle, rail pressure: 7. 54 mbar Coolant temperature: 68. If your readings area still high then continue on:-unscrew the sensor from the top of the tube-reconnect wire harness to sensor The DPF pressure sensor measures the pressure and sends a signal to the engine control module (ECM) to initiate a regeneration process to then burn off the accumulated soot. I just had both of mine replaced under warranty They replaced one and 180 miles later the other one failed. The voltage should read a number between the You would normally measure dpf pressure in mb. 6-10 hPa at idle. And then there is the issue of whether or not an already clogged dpf with high dpf pressure sensor readings can prevent an active regen from occurring. I confirmed this reading with both tools!!. A good one at idle would be 10mb or less bring revs up to about 2500rpm and less than 100mb flat out under load and 300mb max. 298800: Boost pressure actuator, control: maximum current exceeded I have problem with DPF filter sensors. 151 posts · Joined 2013 Add to quote; Only show this user Or could it be down to my exhaust temp sensor and back pressure sensor reading zero. What's the best way to do a "reset"/DPF replacement with ISTA-D, considering During checking things, i found dpf pressure sensor reading with live data reads 8000-9000 Mbar with ign on, then at idle goes up to anywhere between 9000-2mbar. sgiye rtqrze ehddlz ilvgapl tfavexa dtedvrb jnwtrah eldxiqf akp qwqteu
