DTC codes / P08xx · Transmission / P0834
P0834 indicates that the powertrain control module (PCM) has detected a low-voltage condition on the circuit for clutch pedal switch 'B', which is typically the switch that confirms the clutch pedal is fully released. The PCM expects to see a specific voltage on this circuit when the pedal is up, and a voltage below the threshold for a calibrated time sets this code.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
