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 actuator until gear position feedback has been tested directly.

Useful checks before replacing parts

Monitor gear shift position data while commanding or selecting each gear and compare it with actual actuator or lever movement.
Inspect position sensor reference, signal, ground, connector fit, linkage movement, actuator travel, and wiring through flex points.
Check companion gate select, actuator, clutch, or control-error codes to determine whether feedback or motion is failing.
