P2117
Throttle/Pedal Position Sensor F Minimum Stop Performance
Throttle / pedal position
Generic OBD-II
Medium
What it means
P2117 means the PCM sees the "F" throttle/pedal position sensor's minimum (closed) stop reading fall outside the expected range. Often a carbon-fouled throttle bore or a drifting sensor prevents a clean closed position, so the PCM limits power until the true idle stop can be relearned.
Medium
Can I keep driving? Usually driveable, but the car may hold reduced power or limp mode until it's fixed, so keep trips short and avoid demanding driving.
Common symptoms
What you'll notice
- Check-engine light on
- Reduced engine power / limp (failsafe) mode
- Hesitation or poor throttle response
- Rough or erratic idle
Common causes
Most likely first
- Dirty or carbon-filled throttle bore preventing a clean closed (minimum-stop) positionLikely
- Faulty throttle/pedal position sensor 'F'Common
- Open, shorted, or chafed sensor wiringCommon
- Poor connector contact or corrosion at the sensor plugLess often
- Faulty engine control module (ECM), or a jammed floor mat / pedal obstructionLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and check for related throttle codes (P2116, P2168, P2138).
- Inspect and clean the throttle body / bore so the plate can reach its true minimum stop, then clear and re-test.
- With key on, engine off, verify a steady 5-volt reference and a clean ground at the sensor connector; inspect wiring for opens and shorts.
- Perform the throttle/idle relearn procedure after cleaning or reconnecting.
- If readings are still out of range, replace the position sensor or throttle body as specified.
