What P2168 means
P2168 covers position signal F at maximum travel. Letter F only exists where the pedal carries a third sensor track; GM's 2004 engine table, for example, runs a third pedal sensor under the F circuit codes, whereas most current cars make do with two tracks. The code sets when F, with the pedal at its upper stop, reports a value outside the accepted range. No manufacturer documents P2168 publicly; its logic follows P2163, which Ford lists, and the open-stop learning in a Visteon patent. Before ordering a pedal module, confirm that the car has a sensor F and compare all three tracks at full pedal. A worn track, a poor connector contact or a pedal that cannot reach its stop are typical. P2117 tests the rest position of F, P2130-P2133 its circuit.

- Full power not available
Common causes of P2168
- PossibleThird pedal track F worn at full travel
- PossiblePoor contact on the sensor F pins
- PossiblePedal held short of its stop
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2168 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 1 | Area: fuel and air metering. |
| 68 | The exact fault in that area. |
What to do next
- Note P2168 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 P2168
What does P2168 mean?
P2168 means "Throttle/Pedal Position Sensor F Maximum Stop Performance". P2168 covers position signal F at maximum travel. It is a generic code, so it means the same on every make.
Is it safe to drive with P2168?
Drive gently and only to a workshop. With P2168 the car can go into limp mode (reduced power) to protect itself.
Will P2168 fail an emissions test?
Yes, it can. P2168 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 P2168 to fix?
Difficulty: easy. A typical repair takes 0.2 to 1 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P2168 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
