P2CEBParticulate Filter Pressure Sensor D Circuit Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- P2CEB says sensor D reports a pressure that is electrically fine but does not match what the exhaust flow should produce. Ford is the only maker found using it, in its 2024–25 petrol summary for engines with a gasoline particulate filter per bank. The functional check starts only after the electrical tests have passed and uses three tests: after shutdown, once inlet gas has been at 250 °C or more for 600 s, an average reading of 16 to 32 hPa fails the offset test; while running, the rationality test fails once readings at or over the pressure predicted from flow add up to 20 s; and a pressure that does not follow a flow change of more than 225 m³/h within 2 s fails the derivative test. Hoses, condensate and sensor drift are the main suspects; P2CE6 is the C counterpart.
- What you may notice
- Warning lamp on
- Missing substrate test for that bank cannot be completed
- Usually no noticeable change while driving
- Likely causes
- LikelySensing hose to sensor D cracked, kinked or disconnected
- PossibleCondensate in the sensing line after short trips
- PossibleSensor D drifted or responding slowly
- 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: €20 – €350
