How To Correct P2454 Diesel Particulate Filter Pressure Sensor A Circuit Low

  • Make sure to mend the faulty flawed DPF pressure sensor A harness.
  • Repair or replace the quirky DPF pressure sensor A circuit.
  • You must fix the defective DPF pressure sensor tubes/hoses.
  • Rehabilitate the defaults in the diesel exhaust fluid.

What is a DPF pressure sensor?

A diesel particulate filter (DPF) differential pressure sensor measures exhaust backpressure and signals when the power-train control module (PCM) should begin a regeneration process to clear the filter of diesel particulate matter (DPM), or soot.

How do you clean a DPF sensor?

In order to burn it clean, the de-installed DPF is put in a burning oven, where it is heated until all remaining soot is burned to ashes. Subsequently, the filter is blown clean with pressurised air until all ashes are completely removed. Rinsing is in fact blowing the filter clean with a watery cleaning solution.

How does a DPF regenerate?

DPF active regeneration



Active regeneration happens when extra fuel is injected automatically as the filter reaches an approximately 45% full limit. The extra fuel raises the temperature of the exhaust and burns off the stored soot. Yet the journey has to be long enough to complete a full cycle.

Another option is to clean it yourself with an additive. With Lindemann’s Total Care Diesel you can clean your DPF yourself. This product lowers the combustion temperature of soot, making it easier to burn. It also contains a very high level of active cleaning agents.

Can you clean a DPF without removing it?

Never attempt to remove a DPF and to start forced regeneration.
