P0562 on Porsche
System Voltage Low
P0562 on Porsche vehicles indicates system voltage low. Au7o has documented this code across 1 Porsche model — most commonly on Taycan. P0562 means the engine computer detected that the vehicle's system (battery/charging) voltage is too low for normal operation. The computer constantly monitors charging-system voltage because nearly every sensor, injector, and module depends on a stable supply; sustained low voltage can cause erratic behavior and other false codes. This is most often a charging or battery problem — the alternator isn't keeping up, the battery is weak, or there's resistance in the cables/grounds. You may notice dim lights, slow cranking, or multiple unrelated warning lights. Typical repair costs on Porsche range from $200 to $800, depending on the specific model and root cause.
Common Causes of P0562
- •Failing alternator or worn alternator brushes/regulator
- •Weak, old, or discharged battery
- •Corroded, loose, or damaged battery cables and terminals
- •Bad engine or chassis ground connections
- •Slipping, glazed, or broken serpentine/drive belt
- •High resistance in charging system wiring or fusible link
- •Faulty PCM voltage reference or charging-system control
P0562 on Porsche by Model
Porsche Taycan(1 issue)
- 12V Auxiliary Battery Drain2020-2025
The Taycan 12V auxiliary battery drains excessively when the vehicle is parked, even for short periods. The numerous electronic modules and always-on connectivity features draw more current than the 12V battery management system can sustain. A dead 12V battery prevents the car from powering on even with a full high-voltage battery.
