This is the range for the most common fix, alternator replacement. Which repair your car needs depends on a proper diagnosis.
The computer watches the voltage in the car's electrical system, which should sit around 13.5 to 14.5 volts with the engine running. This time it dropped below the allowed low limit while driving. That usually means the alternator is not charging enough or the battery cannot hold a charge.
- Safe to drive?
- Short trips only
- Most common cause
- Failing alternator
Drive only a short distance to a shop; low voltage can stall the car and leave you stranded.

What you may notice
- Dim lights
- Battery warning light
- Slow starting
- Stalling
Common causes, most likely first
- Failing alternator
- Weak or dying battery
- Loose or corroded battery cable
- Worn serpentine belt
- Bad ground
Check this first
Have the battery and alternator load-tested, which many parts stores do for free. Also check that the battery clamps are tight and the cable ends are clean, since a corroded terminal can look like a failing alternator.

Before you pay
- Ask the shop what test showed this part is the cause, not just that the code appeared.
- Ask for parts and labor listed separately, and for the hours.
- Ask for a written OK before any extra work. Many states require written authorization before repairs.

P0562 questions
Is it the battery or alternator?
A load test of the battery and a charging-output test of the alternator will tell them apart. A bad battery can make a good alternator work too hard, so the shop should test both before replacing either.
Why did other lights appear?
Many modules rely on steady voltage. When it dips, they may stop reporting and trip warning lights for ABS, airbags or stability control. These often clear after the voltage problem is fixed.
How far can I drive?
As little as possible. A failing alternator leaves the car running only on battery power, and once it drains, the car can stall with power steering and brakes feeling heavier. Go straight to a shop.
