What P08B6 means
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.
P08B6 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyEasy, DIY possible
- Typical labor0.3 to 1.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P08B6
- Warning lamp on
- Start-stop disabled
- P08B9 correlation code may set alongside
Common causes of P08B6
- Most likelySensor B signal wire shorted to ground
- PossibleLost supply voltage to sensor B (open wire, connector off)
- PossibleFailed clutch pedal position sensor B
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P08B6 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 8 | Area: transmission. |
| B6 | The exact fault in that area. |
What to do next
- Note P08B6 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P08B6
What does P08B6 mean?
P08B6 means "Clutch Pedal Position Sensor B Circuit Low". P08B6 means the signal of the second clutch pedal sensor has dropped below its valid range. It is a generic code, so it means the same on every make.
Is it safe to drive with P08B6?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P08B6 fail an emissions test?
Yes, it can. P08B6 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P08B6 to fix?
Difficulty: easy. A typical repair takes 0.3 to 1.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P08B6 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
