△ DPF differential pressure sensor voltage signal above upper limit/below lower limit
1. Check if the differential pressure sensor circuit is intact and if there are any open or short circuits.
2. Try replacing the differential pressure sensor to verify if it has failed.
Through the above troubleshooting guidance methods, we can gradually identify the cause of the "DPF differential pressure sensor voltage signal abnormality" fault and take corresponding repair measures.
1. Use a multimeter to measure the voltage of the sensor harness (including power, signal, and ground wires) to check for short circuits or open circuits.
2. Conduct sensor cross experiments to verify whether the sensor itself has malfunctioned.
