How do you diagnose a bad DPF sensor?
What to look out for in a failing DPF differential pressure sensor
- Poor engine performance.
- Poor fuel economy.
- High engine temperatures.
- High transmission temperatures.
- An increase in black smoke (soot) from the exhaust.
- Check engine light.
What are DPF codes?
DPF related fault codes
- P1471 Diesel particulate filter (bank 1) regeneration not completed.
- P2002 Diesel particulate filter (bank 1) efficiency below threshold.
- P2003 Diesel particulate filter (bank 1) particulate mass too high.
- P242F Diesel particulate filter (bank 1) regeneration not active.
Will a clogged DPF cause no start?
What’s more, these fumes will smell, which is also a tell tale sign that your DPF filter is clogged. When your engine management unit detects the excess build up of fumes in your engine, it can refuse to start. This is for the safety of the engine, as the ignition process mixing with the fumes can cause major damage.
What are the causes of DPF fault codes?
P2003 Diesel particulate filter (bank 1) particulate mass too high. P242F Diesel particulate filter (bank 1) regeneration not active. P244A Particulate filter differential pressure too low. P224B Particulate filter differential pressure too high. P2452 Particulate filter differential pressure sensor malfunction.
What does DPF do to a diesel particulate filter?
The Diesel Particulate Filter traps the harmful diesel gases that gets cleaned regularly by a process called DPF regeneration. The collected diesel soot particles are burnt off at high temperatures, which results in an “ ash-like ” after product.
What is the DTC code for diesel particulate filter?
If this occurs, the malfunction indicator lamp (MIL) will be illuminated and a diagnostic trouble code (DTC) will be set in system memory. DTC P2002 is defined as “Diesel Particulate Filter (DPF) Efficiency Below Threshold (Bank 1).” What are the common causes of code P2002? Depending on year, make, and model, DTC P2002 may have number of causes.
Why is my diesel engine overcharging for DPF?
Overcharged DPF – Aside from driver habit, DPF overcharging can occur because of a poorly-maintained engine or using fuels with high sulfur content. Some biodiesel blends produce more than normal amounts of soot, which may be excessive for your vehicle.
