What causes DPF pressure sensor failure?
Why do DPF differential pressure sensors fail? As with any electrical sensor in an engine, wires to the ECU can be damaged from harsh vibrations or crack and melt from extreme heat. And just like the DPF, the sensor hoses can also become clogged from soot in the exhaust.
What is normal DPF pressure?
A DPF with a pressure drop characteristic that provides a back pressure of 15 kPa at rated speed and full power would not result in significant performance degradation at full load for all engine speeds for this particular engine.
How do you use a differential pressure sensor?
How does a differential pressure sensor sense pressure? Typically, the two pressures to be measured are applied to opposite sides of a single diaphragm. The deflection of the diaphragm, either positive or negative with respect to the resting state, determines the difference in pressure.
Where is the exhaust pressure sensor?
Usually, you’ll find the sensor bolted onto the side or bottom of the engine, or along the firewall in the back of the engine well.
What is the efficiency of The P2002 particulate trap?
P2002 – Particulate trap, bank 1 – efficiency below threshold Trouble Code Fault Location Probable Cause P2002 Particulate trap, bank 1 – efficiency be Particulate trap
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.
How much pressure can you put on a DPF?
Brilliant DPF causing almost no restriction: 20-99: Good result and typical of a DPF in good working order: 100-250: DPF causing up to 0.25 BAR of pressure – needs investigation: 250-500: Serious restriction probably not allowing car to do a Forced Regen: 500-1000: Performance loss very marked at this level >1000
