P2CEDParticulate Filter Pressure Sensor D Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- 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.
- What you may notice
- Warning lamp on
- Live data shows sensor D at maximum with the engine at idle
- Filter monitoring for that bank incomplete
- Likely causes
- LikelySensor ground open or high resistance
- PossibleSignal wire shorted to 5 V reference or battery voltage
- PossibleSensor D failed with output stuck high
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Medium · Often possible to do yourself.Typical cost: €30 – €350
