P0562 on a Ford: Causes, Fixes & Repair Cost

🟠 Moderate severity · drivable

You can usually drive a Ford for a short time, but a dead charging system will leave you stranded, so have it checked soon.

What P0562 means on a Ford

On a Ford, P0562 means the engine computer sees system voltage below about 10 volts. Newer Fords use a battery management system (BMS) that tracks the battery's state of charge, and a weak battery or failing alternator can set this code.

Is P0562 common on Fords?

P0562 shows up on F-150s, Escapes, and Explorers, often after the battery ages or the alternator starts failing. The BMS on newer Fords can trigger low-voltage codes when the battery is weak even if it still starts the truck, and alternator failure is a common cause on higher-mileage models.

Commonly reported on: F-150, Escape, Explorer, Focus.

Frequently asked questions

Can I drive my Ford with a P0562 code?

Yes, for a short time, as long as it starts. If the alternator stops charging, the battery will die and you will be stranded, so have it checked soon.

Is a weak battery the main cause of P0562 on Fords?

Usually yes. Ford's battery management system is sensitive, so a weak battery can set this code even if the truck still starts. A failing alternator is the next most common cause.

How much does it cost to fix P0562 on a Ford?

A new battery runs about $120–$280. If the alternator has failed, replacement runs about $400–$900.
