P24D0
Particulate Matter Sensor Supply Voltage Circuit Low
The PM sensor supply voltage is below the plausible range. Wiring faults of this kind typically come from chafing, water ingress at connector seals, or pin push-back — a wiggle test on the harness while the code is active often confirms the location.
