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.

Likely causes

Sensor B offset drifted or moisture inside the sensor
Pressure hose kinked or blocked so pressure is trapped
Wiring or connector fault on the sensor B circuit

Symptoms

  • Malfunction indicator lamp on
  • Soot load estimate unreliable, regeneration timing affected
