What is the solution for diesel vehicle DPF regeneration failure?
1 Answers
Diesel vehicle DPF regeneration failure has two solutions: one is regeneration, and the other is direct replacement. Causes of DPF regeneration failure: Excessive particulate matter adsorbed by DPF, high signal voltage feedback from differential pressure sensor to ECU, circuit issues, DPF blockage, differential pressure sensor failure, ECU malfunction. Reasons for frequent DPF regeneration: Use of low-quality gasoline containing excessive impurities and carbon compounds that easily clog the DPF, failure to use low-ash engine oil (which contains fewer impurities and reduces DPF clogging probability), and prolonged low-speed driving which decreases fuel combustion efficiency.
