Feng Jun 5 Throttle Data Flow

Please refer the diagnosis expert to read the fault code, which shows that there are currently two faults:

Particles in the DPF are overloaded.

P 2463:DPF particle mass deviation (measured value-simulated value) exceeds the upper limit of secondary monitoring.

02: Fault Code Analysis

The literal meaning of the fault code is that DPF absorbs too many particles, but in fact, the signal voltage fed back to ECU by the differential pressure sensor is too high, which may be caused by the following aspects, which we mainly consider when troubleshooting.

① Circuit problems

②DPF blockage

③ The differential pressure sensor is faulty.

④ECU failure (rare)

When the first fault is reported, the warning light will be lit and the ECU will call the torque limit function to limit the engine. I'm afraid that's why the car lacks power. Now that we have found the reason, let's cut the crap and start solving the fault code.
