P2163Throttle/Pedal Position Sensor A Maximum Stop Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- 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.
- What you may notice
- Check engine and throttle warning lamps on
- Engine does not reach full power
- Limp mode with limited throttle opening
- Likely causes
- 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
- RareContact resistance in the sensor connector shifting the signal
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
