To diagnose the P244A code, it typically requires 1.0 hour of labor. The specific diagnosis time and labor rates at auto repair shops can differ based on factors such as the location, make and model of the vehicle, and even the engine type. It is common for most auto repair shops to charge between $75 and $150 per hour. The Diesel Particulate Filter (DPF) is housed in the exhaust and is designed to capture the soot particles emitted from modern diesel engines. Sadly, many of the DPF equipped cars are developing problems due to the DPF either failing, clogging up or just failing to carry out a regeneration properly. Ash accumulation is a side effect of DPF filtration and regeneration. This is caused by the frequent use of non-flammable materials such as lubricant additives, trace elements in diesel fuel / additives, and debris from engine wear and corrosion. Ash usually accumulates along the walls of the DPF or in plugs near the rear of the filter element. Silverado HD and GMC Sierra HD vehicles that are equipped with 6.6L Duramax Diesel engines (RPO LML or LGH) may contain a leak in the seal between the engine-exhaust down pipe and the engine-exhaust pipe. If a leak is present, the intermittent regeneration of the diesel-particulate filter Particulate physics. My 88,000-mile March 2008 Mondeo automatic diesel estate requires a new DPF and a sensor that goes with it. The price of the filter from the Ford main dealer is £1,297 plus VAT (which allows £200 for the return of the old DPF) and the sensor is £116.68 plus VAT.
The way it's intended to work is that when the particulate matter (PM) in the Diesel Particulate Filter (DPF) reaches a certain value, the DPF warning light should illuminate to indicate you need to keep the revs up at about 2000rpm for 15 to 20 minutes to clear it. If the vehicle is driven normally whilst the light is on, PM will increase
What are the Possible Causes of the DTC P242F? NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes. Diesel Particulate Filter is full of ash. Damaged Diesel Particulate Filter pressure sensor. Faulty Exhaust Gas Temperature (EGT) A DPF filter (Diesel Particulate Filter) is installed in your car to trap diesel particulate matter, also known as soot, in the exhaust system. This prevents your exhaust from polluting black fumes into the atmosphere. If there is black smoke leaving your exhaust pipe, this is an obvious indicator that your DPF filter is not working properly Diesel Particulate Filter Operation in Heavy Duty Diesel After Treatment Systems - On Highway tpnlvZE.
