  • A sensor F that lost its calibration
  • A valve sticking and holding pressure at sensor F
  • A failing sensor F with an unstable signal

What to do next

  1. Compare brake pressure sensor F with the other pressure sensors on live data
  2. Bleed the hydraulic circuit if air is suspected near sensor F
  3. Inspect the sensor F connector and wiring for damage
