P245FParticulate Filter Pressure Sensor B 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
With P245F the controller decides that the sensor B value is electrically fine but makes no physical sense. Ford's 2024 gasoline strategy runs three such tests on the B sensor of the gasoline particulate filter: an offset check with the engine stopped that fails once the average reaches 16 to 32 hPa; a rationality check that fails when the reading stays at or above the pressure expected for the current exhaust flow for a total of 20 s; and a derivative check that compares how fast pressure follows a change in flow over 2 s. Jeep released PCM software for 2018 Wranglers with a gasoline filter in Asia-Pacific and EMEA markets that set P245F together with P2453. Deutz assigns P245F to the pressure after the filter leaving its physical limits. Hoses, condensate and sensor drift are the usual suspects. Circuit codes are P245E, P2460 and P2461.
What you may notice
  • Malfunction indicator lamp on
  • Filter regeneration triggered too early, too late or blocked
Likely causes
  • LikelySensor B hose cracked, disconnected or blocked
  • PossibleCondensate in the pressure line falsifying the reading
  • PossibleSensor B drifted out of calibration
  • RareControl software needing an update (some Jeep models)
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
Repair
Easy · Often possible to do yourself.Typical cost: €20 – €400
