P0562 on a Honda: Causes, Fixes & Repair Cost

🟠 Moderate severity · drivable

You can usually drive a Honda for a short time, but if the alternator stops charging the battery will die and the car may stall, so get it checked soon.

What P0562 means on a Honda

On a Honda, P0562 means the engine computer sees system voltage below about 10 volts. Hondas use an electronic load detector (ELD) to manage charging, so a weak battery or failing alternator can confuse the charging system and set this code.

Is P0562 common on Hondas?

P0562 is most common on Accords, Civics, and CR-Vs where the battery has aged past four or five years. Honda's ELD-based charging is sensitive, so even a marginal battery can trigger low-voltage codes, and failing alternators become more common on older models with higher mileage.

Commonly reported on: Accord, Civic, CR-V, Pilot.

Frequently asked questions

Can I keep driving my Honda with a P0562 code?

Yes, for a short time, as long as it starts. If the charging system fails, the battery will drain and the car can stall, so have it checked soon.

Why does P0562 show up on Hondas?

Aging batteries are the most common cause. Honda's electronic load detector makes the charging system sensitive, so a weak battery can set this code even when the car still starts.

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

A new battery runs about $120–$250. If the alternator has failed, replacement runs about $400–$900.
