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 before proving the high position signal is not caused by wiring or reference faults.

Useful checks before replacing parts

Check position sensor signal, reference, ground, connector continuity, open circuits, short-to-voltage faults, and module input voltage.
Inspect sensor connector fit, linkage or actuator travel, harness damage, water intrusion, and recent transmission service areas.
Compare live gate position data with commanded movement to determine whether the high signal is fixed or movement-related.
