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 diagnose a shift internal fault before confirming that the shifter Y signal is accurate.

Useful checks before replacing parts

Monitor gear lever Y position during every shifter movement and compare the data to actual lever travel and detents.
Check sensor reference voltage, ground, signal continuity, connector condition, linkage movement, and contamination inside the shifter.
Review companion X position, range sensor, or manual-mode codes to identify whether the shifter assembly has a shared fault.
