Q: What does code P1797 mean?

Clutch Pedal Switch MT Or P/N Switch Circuit Fault. P1797 on Kia vehicles indicates that the powertrain control module (PCM) has detected an implausible signal from either the clutch pedal position switch on manual-transmission models or the park/neutral (P/N) position switch on automatic models. The PCM expects a specific voltage state when the clutch is depressed or the transmission is in Park or Neutral, and it sets this code when the circuit stays open, stays grounded, or toggles erratically.
