P0562 on Honda
System Voltage Low
P0562 on Honda vehicles indicates system voltage low. Au7o has documented this code across 4 Honda models — most commonly on Accord, Element, Pilot. 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 Honda range from $200 to $850, 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 Honda by Model
Honda Accord(1 issue)
- Alternator / Charging System Failure - Battery Light and Dimming2008-2017
The alternator (or its integrated voltage regulator) commonly wears out around 100,000-150,000 miles, showing a battery/charging warning light, headlights and dash lights that dim at idle and brighten with revs, and eventually a no-start from a dead battery. On 9th-gen cars a persistent 'check charging system' light can also stem from the battery-management sensor (see the 17V-418 recall) rather than the alternator, so the charging fault must be pinpointed before parts are replaced.
Honda Element(1 issue)
- Alternator Failure2003-2011
Alternator diode failure causing persistent battery drain even after replacement. Common failure point around 140k miles. OEM Honda alternators strongly preferred over aftermarket by Element community - aftermarket often fail prematurely. Test with multimeter (should read 13.5-14.5V running). Check battery connections for corrosion first. Replace serpentine belt while doing alternator work if worn.
Honda Pilot(1 issue)
- Parasitic Battery Drain Causing Dead Battery2016-2023
Honda Pilots experience excessive parasitic battery drain (over 80mA) causing dead batteries after 24-48 hours. Common causes include radio/audio staying active when off, Bluetooth module constantly searching, and AC compressor clutch relay sticking on. Normal draw should be 12-30mA. Vehicle requires 30+ minutes to fully "fall asleep" with hood, doors, and trunk closed.
Honda S2000(1 issue)
- Alternator Failure2000-2009
Alternator can fail at 80,000+ miles, preventing battery charging. Internal voltage regulator (AP2 especially) can malfunction. AP1 and AP2 alternators are interchangeable. Symptoms include battery discharge, charging light illuminated, dimming headlights under load, weak starter cranking. OEM replacement recommended for reliability over remanufactured units.

What does P0562 mean on Honda?▼
P0562 stands for "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. On Honda specifically, this code is documented across 4 models.
