P087EClutch Position Sensor B Circuit Intermittent
- Generic OBD-II code · Powertrain

- How the car detects it
- Clutch position sensor B reports the position of the second clutch or its actuator, the counterpart of sensor A (P0805 ff). The only documented user is Ford's dry DPS6 dual clutch in Fiesta and Focus: clutch B, for reverse and the even gears, is moved by a three-phase motor whose Hall sensors give its position, and the gearbox module drives it through an internal motor driver. Ford sets P087E for a sequence fault: when the clutch B motor turns, its three Hall sensors produce a fixed pattern; if a step is skipped or the order is wrong, motor and clutch position become unreliable. Typical are sporadic Hall dropouts and loose contacts. The counterpart for clutch A is P0809.
