P0562 on Nissan
System Voltage Low
P0562 on Nissan vehicles indicates system voltage low. Au7o has documented this code across 3 Nissan models — most commonly on 370Z, Leaf, Sentra. 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 Nissan range from $100 to $700, 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 Nissan by Model
Nissan 370Z(1 issue)
- Premature Battery Discharge / Weak OEM Battery Leading to Intermittent No-Start2021-2023
A number of late-production 370Z owners report weak-battery and intermittent no-start complaints, especially on low-mileage cars that sit for extended periods. The problem is often not a major module failure but a marginal factory battery, storage-related sulfation, or parasitic draw from accessories/dashcams after the car sits. Symptoms can mimic starter or clutch-switch faults, but voltage testing usually reveals a weak battery state.
Nissan Leaf(1 issue)
- 12V Auxiliary Battery Drain and Failure2011-2024
The Leaf's small 12V auxiliary battery drains and fails frequently, sometimes within 2-3 years. The telematics system, Carwings/NissanConnect, and other modules draw power even when the car is off. If the 12V dies, the car cannot be turned on despite the traction battery being fully charged. This is the #1 most-reported issue on Leaf owner forums across all model years.
Nissan Sentra(1 issue)
- Intermittent No-Start or Engine Stall Linked to Stop/Start and 12V Battery Weakness2023-2025
A recurring owner complaint on newer Sentras involves weak factory batteries, hard starting, no-start conditions, or stalling/rough restart behavior associated with the idle stop/start system. The problem often appears early in ownership and may be aggravated by short-trip driving or battery state-of-charge issues. In some cases, owners report multiple jump-starts or battery replacement within the first few years.

What does P0562 mean on Nissan?▼
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.
