P2CED Particulate Filter Pressure Sensor D Circuit High

With P2CED the analog output of filter pressure sensor D lies above its usable top end. Ford's gasoline OBD document for 2024–25, with filters on both banks and up to four pressure sensors, sets the code above 4.73 V lasting 5 s. That usually traces back to an open sensor ground, a signal line touching the 5 V reference or battery voltage, or an open signal wire on an input with a pull-up. A real pressure that high would mean an almost fully blocked filter, which the separate functional test P2CEB and the restriction monitor would show differently. No other maker documents sensor D; GM's diesel tables only cover C (P2CE8). Disconnecting the sensor and watching the reading jump helps locate the fault side. The low-voltage code is P2CEC.

Likely causes

Sensor ground open or high resistance
Signal wire shorted to 5 V reference or battery voltage
Sensor D failed with output stuck high

Symptoms

  • Warning lamp on
  • Live data shows sensor D at maximum with the engine at idle
  • Filter monitoring for that bank incomplete
