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 clear intermittent shifter position codes without reproducing the signal dropout.

Useful checks before replacing parts

Record Y position data while moving through all lever positions and repeat while gently flexing the shifter harness.
Inspect sensor connector fit, console contamination, linkage play, wire strain points, terminal corrosion, and reference or ground stability.
Compare the intermittent Y signal to range, gear display, and manual-mode behavior to locate the failure point.
