How do I Fix code P242F?
How To Correct P242F Diesel Particulate Filter Restriction – Ash Accumulation
- DPF replacement.
- Check for faulty sensors, circuit and wiring issue and resolve them immediately.
- Clean the diesel particulate filter properly.
- PCM might need reprogramming.
What is code P242F?
When a P242F error code is stored, it means that the powertrain control module (PCM) has detected a level of ash restriction in the diesel particulate filter (DPF) deemed to be restrictive. Ash accumulation is a side effect of DPF filtration and regeneration.
What is a u1900 code?
The u1900 fault code refers to a manufacturer specific code that is categorized by Ford, and is caused when there is a failure in the communication bus. When it fails to receive a specific error, or cannot relay that message to the powertrain control module, it usually displays this error code.
How do you remove ash from DPF?
DPF manufacturers have recommended a variety of filter cleaning techniques to remove the accumulated ash. A standard method for cleaning DPFs is using “Bake and Blow” machines, which routinely yields ash that can be categorized as Non RCRA Hazardous Waste based on the amount of zinc it contains.
What does code b1318 mean?
Ford error code b1318 indicates that the battery voltage is low, and is typically caused by a dead or dying battery or a faulty battery connection.
Do DPF cleaners remove ash?
While pneumatic cleaning processes can be effective in removing ash accumulated in a layer along the DPF channel walls, complete removal of the ash plugged sections is often difficult.
What causes ash build up in DPF?
Ash accumulates in the DPF over extended use, as the incombustible material left behind following filter regeneration and soot oxidation. The ash consists of various metallic compounds originating from lubricant additives, trace elements in the fuel, and engine wear and corrosion products.
How much does it cost to clean DPF filter?
Cold starts also create the need for more frequent DPF cleanings, which shorten DPF effectiveness and, ultimately, lifespan. Factor in downtime for cleaning DPFs and replacement costs can range between $2,500 to $8,000 per vehicle.
What does the p242f Ford code mean?
| What is P242F FORD code meaning? The Powertrain Control Module ( PCM) monitors the pressure decrease at the diesel particulate filter following a diesel particulate filter regeneration for a concern. The PCM calculates the amount of ash and the pressure increase the ash generates in the diesel particulate filter.
What does the OBD II fault code u2023 mean?
What Does Code U2023 Mean? OBD II fault code U2023 is a manufacturer specific code that is defined by car maker Ford as “Fault Received From External Node”, and is set when the PCM (Powertrain Control Module) detects an input from any other control module on the vehicle that falls outside of an expected range, value, or voltage.
What does p242f mean in diesel particulate filter?
On rare occasions, when I have discovered a stored P242F code, it has meant that the powertrain control module (PCM) has detected a level of ash restriction in the diesel particulate filter (DPF) deemed to be restrictive. This code is used exclusively in diesel powered vehicles.
When to change the DPF code p242f?
Code P242F will set when the soot / ash levels in the aftertreatment diesel particulate filter system have went beyond the most severe possible. Correction requires DPF replacement.
