DTC codes / Chrysler codes / P1680
P1680 on Chrysler vehicles indicates that the powertrain control module (PCM) has detected an open or shorted circuit in the clutch released switch signal. The PCM expects to see a specific voltage when the clutch pedal is released, and the code sets when the circuit stays outside that expected range for a calibrated time.
Guidance is general and written for Chrysler vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
