Code details

Generic OBD-II · P0

System: Transmission
Code type: Generic (SAE / ISO controlled)

Diagnostic boundary

A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.

Do not replace the clutch pedal assembly until the high switch B circuit has been isolated.

Symptoms of P0835

Harsh, delayed, or slipping shifts, or being stuck in one gear.
Check-engine light, sometimes with limp-home mode.
Flaring RPM or a shudder under load.

Common causes of P0835

Low or degraded transmission fluid.
A failing speed sensor, shift solenoid, or pressure-control circuit.
Wiring, connector, or internal hydraulic/mechanical faults.

Useful checks before replacing parts

Check switch B signal voltage, ground integrity, open-circuit faults, short-to-voltage faults, connector spread, and switch adjustment.
Monitor both clutch switch signals during pedal movement and confirm that their transition points match service information.
Review starting, cruise cancel, shift assist, and rev-match behavior for symptoms tied to the high switch B signal.
