P2CEAParticulate Filter Pressure Sensor D Circuit
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- Sensor D is the fourth slot for particulate filter pressure and only appears in Ford's 2024–25 petrol OBD summary, which watches a filter on each bank (missing substrate codes P226D and P226E); Ford does not say publicly which letter belongs to which filter or tap. For a digital SENT sensor D, P2CEA covers any circuit failure, monitored without pause with 5 s to register, while lost communication with the same sensor is U0697. GM's 2025 diesel tables stop at sensor C, where P2CE5 is an offset test instead. CARB requires such inputs to be monitored for circuit faults. A damaged connector, a harness melted by exhaust heat or a failed sensor are the likely finds. Without the value, back pressure for that filter is only estimated and the substrate check may not run.
- What you may notice
- Warning lamp on
- Particulate filter monitoring for one bank incomplete
- Usually no change in driveability
- Likely causes
- LikelyDamaged or corroded connector at sensor D
- PossibleHarness to sensor D damaged by exhaust heat
- PossibleSensor D internally faulty
- 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: €40 – €350
