P0562 Code: System Voltage Low
P0562 means vehicle system voltage is lower than expected. Learn the common symptoms, causes, severity, and typical repair costs.
The P0562 code means vehicle system voltage is lower than expected. It is stored when the engine computer sees a signal or operating condition outside the expected range.
Vehicle speed, idle, and voltage codes affect drivability systems that depend on stable speed data, idle control, and electrical power. The right fix depends on live data, freeze-frame information, service history, and whether other codes are present.
Symptoms
- Battery warning light
- Slow cranking
- Dim lights
- Multiple warning lights
- Stalling
- Electrical accessories malfunctioning
Common Causes
- Weak battery
- Failing alternator
- Loose battery terminals
- Corroded ground cable
- Slipping serpentine belt
- High electrical load or wiring issue
Severity
High if the voltage continues dropping. Low system voltage can cause stalling, no-starts, and false warning lights.
Typical Repair Costs
$50 to $900
- The lower end usually covers inspection, cleaning, wiring repair, or a simple sensor replacement.
- The higher end applies when parts are hard to access or when the code is caused by a larger mechanical, emissions, or transmission problem.
- Always diagnose before replacing parts, because one code can be triggered by several related systems.
Frequently Asked Questions
What does code P0562 mean?
P0562 means vehicle system voltage is lower than expected. The exact cause should be confirmed with diagnostic data before replacing parts.
Can I drive with a P0562 code?
It depends on symptoms. If the car runs poorly, overheats, stalls, shifts harshly, or the check engine light flashes, limit driving and diagnose it promptly.
What is the most common fix for P0562?
Common fixes include addressing weak battery, failing alternator, loose battery terminals, but testing is needed to avoid replacing the wrong part.
