P245EParticulate Filter Pressure Sensor B Circuit
- 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
- Which sensor is B depends on the maker. Ford's 2013 6.7 L Power Stroke has an exhaust pressure sensor ahead of the filter as A and a two-port differential sensor across it as B. Despite its circuit title, P245E is there an offset test during after-run, with the key off and the controller still awake: since no gas flows, the differential reading should be zero, and more than 1 kPa for one second sets the code. On Ford's 2024 gasoline particulate filters with digital SENT sensors, P245E is the general circuit fault, detected within 5 s, while lost communication with the same sensor is U0602. So a sensor that drifted, a hose still holding pressure or water inside the sensor can set it as easily as a wiring fault. Low and high signals have their own codes, P2460 and P2461, and erratic signals P2462.
- What you may notice
- Malfunction indicator lamp on
- Soot load estimate unreliable, regeneration timing affected
- Likely causes
- LikelySensor B offset drifted or moisture inside the sensor
- PossiblePressure hose kinked or blocked so pressure is trapped
- PossibleWiring or connector fault on the sensor B circuit
- 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 – €400
