Code P0C4E: Drive Motor A Position Exceeded Learning Limit
Diagnostic & Technical Explanation
Code P0C4E sets when the drive motor position sensor learning routine cannot complete successfully — the learned offset needed to correlate the resolver's electrical angle with the motor's mechanical rotor position exceeds the allowed limit. The most common physical causes are a resolver that shifted position during a prior service procedure, a marginal resolver excitation signal, and running the learn procedure without meeting the manufacturer's required preconditions.

This is the first procedure in the authored
consideration order, not a measured cause likelihood. Execute it only when its prerequisites
and diagnostic findings support it. Its cost and labor estimates (where known), the step-by-step procedure and the
remaining 2 procedure(s) are in the licensed dataset. Ordering context.
