P08B6Clutch Pedal Position Sensor B Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- P08B6 means the signal of the second clutch pedal sensor has dropped below its valid range. Ford lists it in the 2020–23 gasoline OBD summary under dual PWM clutch sensors, together with P08A9/P08AA for sensor A, P08B7 for sensor B high and P08B9 for the A/B comparison; monitoring runs continuously and needs less than one second to flag a fault. Ford does not mark the code as non-MIL, unlike its clutch switch codes. For a PWM sensor, low usually means the output is stuck at ground (no pulses or 0 % duty cycle), caused by a short to ground, a lost supply or a dead sensor. GM's published tables have no sensor B. The driver mainly notices a warning lamp and missing start-stop.
- What you may notice
- Warning lamp on
- Start-stop disabled
- P08B9 correlation code may set alongside
- Likely causes
- LikelySensor B signal wire shorted to ground
- PossibleLost supply voltage to sensor B (open wire, connector off)
- 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
