P0562: System Voltage Low
16 vehicles · 11 makes · $10-$3,000 repair
Most Reported On
P0562 is an OBD-II diagnostic trouble code meaning “System Voltage Low.” 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. This code is most commonly reported on 2022-2024 Jeep Grand Wagoneer, 2007-2012 Hyundai Veracruz, and 2007-2009 Hyundai Entourage, plus 13 other vehicles, with repair costs ranging from $10 to $3,000.
