Ford Vans and other vehicles. The ECU will start a regen cycle IF the vehicle meets the min speed required of 30 mph. At that time the ECU will spray fuel into the exhaust and that will cause the temperature in the DPF to rise high enough to burn off the Soot. If your speed keeps dropping below 30 mph the regen cycle will fail.
This will put the engine in the right conditions for a DPF regen cycle, which will burn off accumulated PM emissions. Caution: Carry a fire extinguisher. Most manufacturers recommend replacing the DPF if it is charged to more than 75% capacity, which can be determined with a scan tool. Attempting to force a DPF regen on an overcharged DPF can
A forced regen occurs when soot builds up inside the diesel particulate filter (DPF) to the point that the vehicle is no longer operable. When this happens, a driver has to pull over and initiate a self-cleaning process that can take up to 40 minutes — valuable time that could have been spent on the road. But forced regens don’t have to be Engine Coolant Temperature between 50 and 140 C. Intake air temperature between -70 and 250 C. Fueling from -1 to 165mm3. Vehicle speed from -1 to 160 km/hr. No active DTC related to EGR, Indirect injector, or Throttle (boost) The vehicle does not have a soot level sensor to determine how much soot is in the DPF. . 439 26 322 200 79 39 169 444
