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 perform repeated relearns without fixing signal range or mechanical adjustment problems.

Useful checks before replacing parts

Graph clutch position data through the full pedal or actuator travel and compare it with expected learned limits.
Inspect sensor adjustment, pedal free play, linkage wear, wiring, connector tension, and reference voltage stability.
Check whether the code follows clutch service, pedal work, actuator replacement, or calibration loss.
