Order of inspection
P0850 Park/Neutral Switch Input Circuit Medium
The P0850 code means the computer is not getting a consistent signal from the switch that says whether the shift lever is in park or neutral. The typical symptom is an engine that will not start in one of those positions but starts in the other. Most of the time it is a switch adjustment, not a failed part.
