What P2163 means
P2163 concerns position signal A at the upper end of its travel: with the throttle or pedal resting on its maximum mechanical stop, the reading or the learned full-open value lies outside the band the calibration accepts. On Ford layouts A is the first throttle body sensor, while D to F belong to the pedal. Ford lists P2163 for the 2014 Boss 302S with MIL and wrench lamp. A Visteon patent shows the idea: the motor presses the plate onto its fully open stop for about 60 ms, the sensor value is stored, and a learned stop outside roughly 80 to 110 degrees is reported as a failure. Carbon, a bent stop or a worn sensor track are typical causes. P2109 is the matching closed-stop check; P2164-P2168 test the other letters. Reduced power is possible.
P2163 at a glance

- Repair difficultyMedium, DIY possible
- Typical labor0.3 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2163
- Check engine and throttle warning lamps on
- Engine does not reach full power
- Limp mode with limited throttle opening
Common causes of P2163
- Most likelyCarbon or a bent stop keeps the plate from reaching full opening
- PossibleSensor A track worn at the full-open end
- PossibleReplacement throttle body not matching or not relearned
- Less likelyContact resistance in the sensor connector shifting the signal
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2163 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. |
| 63 | The exact fault in that area. |
What to do next
- Note P2163 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 P2163
What does P2163 mean?
P2163 means "Throttle/Pedal Position Sensor A Maximum Stop Performance". P2163 concerns position signal A at the upper end of its travel: with the throttle or pedal resting on its maximum mechanical stop, the reading or the learned full-open value lies outside the band the calibration accepts. It is a generic code, so it means the same on every make.
Is it safe to drive with P2163?
Drive gently and only to a workshop. With P2163 the car can go into limp mode (reduced power) to protect itself.
Will P2163 fail an emissions test?
Yes, it can. P2163 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 P2163 to fix?
Difficulty: medium. A typical repair takes 0.3 to 2 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P2163 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
