How your codes relate
- There is a system voltage problem. Check the battery and alternator before anything else: incorrect voltage causes false codes in many sensors.
The order below is the recommended one: first the codes that can cause the others. After each repair, clear the codes and check which ones come back.
Order of inspection
P0563 System Voltage High High
The P0563 code means system voltage is too high, usually because of a faulty alternator voltage regulator. Overvoltage can damage the battery and the electronics.
