Sometimes the DPF is genuinely getting full, and the sensor is reading a real high pressure difference—but the ECU flags it as “implausible” because the rate of change is too fast, or the values don’t match other engine parameters (like air mass). This is rarer but possible. : In some cases, a DME (Engine Control

Leaves, ice, or road debris stuck in the shutter mechanism, causing the motor to lock up and trip the "short to ground" error.
