Missing sensor prs0: what to test before replacing parts
prs0 is a pressure-related sensor token used in panic diagnostics. On some families it points technicians toward a charging/dock assembly path, but mapping must remain model-aware.
First diagnostic path
- Verify prs0 and the device identifier in the same log.
- Inspect the charging assembly and connector for the exact model.
- Use a correct known-good flex as a reversible confirmation test.
Other causes to keep in scope
- Incorrect aftermarket or revision-mismatched flex.
- Liquid damage, cracked trace or displaced connector pin.
- Board-side communication or supply fault.
How CoreMatch uses this signature
The analyzer combines this token with the panic family, exact device model and compatible verified evidence. It ranks a likely component only when those signals agree, then provides confirmation steps.
Important limitation
Do not treat prs0 as a universal “replace dock” instruction; confirm the electrical path first.
