What P08B7 means
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.
P08B7 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 P08B7
- Warning lamp on
- Start-stop disabled
- Sensor B reading pinned at maximum in scan tool data
Common causes of P08B7
- Most 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
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P08B7 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. |
| B7 | The exact fault in that area. |
What to do next
- Note P08B7 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 P08B7
What does P08B7 mean?
P08B7 means "Clutch Pedal Position Sensor B Circuit High". P08B7 is set when the second clutch pedal sensor reports a value above its valid range. It is a generic code, so it means the same on every make.
Is it safe to drive with P08B7?
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 P08B7 fail an emissions test?
Yes, it can. P08B7 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 P08B7 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 P08B7 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
