P2460 means the analog output of pressure sensor B has fallen below the lowest voltage a working sensor can deliver. On Ford's 2013 6.7 L diesel, sensor B is the differential pressure sensor across the filter; its output runs from about 0.45 V at zero to roughly 4.8 V near 38 kPa, and anything under 0.10 V for 2 s with the key on, battery between 9 and 16.25 V, sets the code. Ford's 2024 gasoline filter strategy uses a higher floor of 0.3 V held for 5 s. A missing 5 V reference, a grounded signal wire or an open in the signal line pulled down inside the controller all look the same here, so a check of reference, ground and signal at the connector comes first. The soot estimate loses one input and regeneration planning gets less accurate. The high case is P2461, erratic signals P2462.

Likely causes

5 V reference to sensor B missing or shorted
Signal wire chafed and shorted to ground
Sensor B internally failed with output stuck low

Symptoms

  • Malfunction indicator lamp on
  • Regeneration based on a model only, possibly more frequent
