P0562 P0562 System Voltage Low
What P0562 means for you
Both sources align on a low severity.
Symptoms
- The P0562 code typically triggers the Check Engine Light on the dashboard, often accompanied by a battery or charging light.
- You may experience issues with electrical functions such as fuel injection and power steering, leading to performance declines.
- Inadequate voltage can result in poor engine performance, affecting fuel mixture and ignition timing, which may reduce fuel efficiency.
- In extreme cases, the engine might stall completely, and automatic transmission vehicles could face shifting difficulties.
Common causes
- A common reason for the P0562 code is a malfunctioning alternator or voltage regulator, which can lead to excessive battery drainage.
- Loose or corroded wiring connected to the alternator can also contribute to this issue.
- High resistance in battery cables may cause voltage inconsistencies within the system.
- Blown fuses or an aging battery can trigger the P0562 code as well.
- In rare instances, a defective PCM can set this code.

The P0562 code indicates a drop in the vehicle's voltage supply, detected by the Power Control Module (PCM). This code is activated when the voltage falls below a critical threshold, which can disrupt the functionality of various electrical systems in the vehicle. Proper voltage levels should be maintained around 13.5 to 15 volts when the engine is running, and drop to at least 12.4 volts when off. Monitoring voltage is crucial for the effective operation of all vehicle systems.
Frequently asked questions
It is not advisable to continue driving with a P0562 code, as it can lead to engine stalling and malfunctioning electrical systems.
Repair costs can vary widely depending on the cause, but fixing issues related to the alternator or wiring may range from $100 to $500.
Symptoms include the illumination of the Check Engine Light, battery light, poor engine performance, and shifting issues in automatic transmissions.
Common causes include a faulty alternator, corroded wiring, high resistance in battery cables, blown fuses, or a defective PCM.
While it is classified as low severity, it can lead to significant issues if not addressed, including engine stalling.
