P0562 on Ford
System Voltage Low
P0562 on Ford vehicles indicates system voltage low. Au7o has documented this code across 2 Ford models — most commonly on Bronco, Transit. 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 Ford range from $200 to $1,000, 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 Ford by Model
Ford Bronco(1 issue)
- Battery Drain and No-Start from Parasitic Electrical Draw2021-2024
A recurring owner complaint on newer Broncos is unexpected battery discharge after sitting, sometimes leading to a no-start condition, multiple warning messages, or modules behaving erratically. Reports often mention the vehicle being parked for only a few days before the battery is too weak to crank, with some cases linked to software/module sleep issues or accessory loads. The problem is documented in owner forums and complaint databases, though root causes can vary by vehicle.
Ford Transit(1 issue)
- Alternator Premature Failure and Voltage Regulator Issues2015-2022
Ford Transit vans experience premature alternator failure, often between 50,000-80,000 miles. The internal voltage regulator fails first, causing undercharging or overcharging conditions. Commercial Transit vans with aftermarket upfitter packages (extra lighting, inverters, refrigeration units) are particularly susceptible due to sustained high electrical loads. Symptoms often start as intermittent battery warnings before progressing to a no-start condition.
