PTO Speed Selector Sensor/Switch 1 Range/Performance
The selector input is electrically intact but the value is implausible — multiple positions asserted at once, or a value that cannot map to any of the configured speed presets. Often a sticky multi-position switch or a contaminated rotary contact.
