P08B7Clutch Pedal Position Sensor B Circuit High

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Matters for the ITP
How the car detects it
P08B7 is set when the second clutch pedal sensor reports a value above its valid range. Ford uses it on vehicles with two PWM clutch pedal sensors, as listed in its 2020–23 gasoline OBD summary next to P08B6 (sensor B low), P08A9/P08AA (sensor A) and P08B9 (A/B correlation); the check is continuous and decides within one second. The clutch switch codes on the same page are marked non-MIL, the sensor codes are not. With a PWM output, high typically means the line is held at its pull-up level (100 % duty cycle), which points to an open signal or ground wire or a short to voltage. GM's published tables cover sensor A only. Effect for the driver: warning lamp, start-stop locked out.
What you may notice
  • Warning lamp on
  • Start-stop disabled
  • Sensor B reading pinned at maximum in scan tool data
Likely causes
  • LikelyOpen signal or ground wire of sensor B, leaving the input at its pull-up level
  • PossibleSensor B signal shorted to a voltage source
  • PossibleFailed clutch pedal position sensor B
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: €50 – €300
