The power control module is designed to alert you when there is an issue with your vehicle. It will display a fault code if it detects an issue. This helps you to diagnose the problem and fix it. The PCM will record a fault code P0562 if there is an insufficient voltage in your system. The PCM will record the code if the voltage drops below 10.0 Volts at idle for more than 60 seconds. All electrical components of your car need a power supply to operate. The battery provides the electrical current required to run certain vehicle functions when the engine is turned off.
The alternator is activated when the engine starts. Its primary job is to maintain a constant supply of voltage, usually between 13.5 and 15 volts. The voltage can change depending on whether the vehicle’s engine is running or idling, as well as the number of electrical devices that are turned on.
The system should have at least 12.4 volts when the engine is turned off. When the vehicle is in motion, the battery must receive between 13.5 and 15.0 volts. The charging system of a vehicle is designed to maintain the normal voltage range between 14.1 and 14.4 volts when the vehicle is idling without the headlights on.
The P0562 code is activated if the PCM detects a sudden drop in voltage.

What are the possible causes of fault code P0562?
It is important to learn about the causes of the P0562 error code before you begin to look for solutions. Troubleshooting is easier when you know the possible causes. The P0562 code’s possible causes may vary depending on the make and model of your vehicle. Most common problems that can trigger the P0562 error code include:
- Alternator (charging-dynamo), voltage regulator or faulty alternator
- Alternator cables that are loose or worn out
- A loose or worn out alternator drive belt
- High resistance battery cables
- Blown fuse
- Battery charge insufficient
- Positive or negative terminals that are loose
- PCM malfunction (rare)
What are the symptoms of fault code P0562?
- Engine fault light illuminated- Battery or charging systems fault light illuminated
- Electrical components may not work properly
- Interior and headlights flickering or dimming
- Sound system shutting off or cutting out
- Intermittent engine stalling (as voltage drops)
- Engine fails to start
- Poor engine performance
- Fuel consumption increases
- Gear shifting faults or failure to change gears (automatic Transmission)
These symptoms are often caused by other codes or problems within the vehicle. You can assume the battery is defective if the engine does not start at idle. There are many issues that can be caused by a P0562 error code. It is best to consult a professional to diagnose the issue.
How to Fix Error Code P0562?
- Replace the alternator if it is faulty or loose.
- Replace the battery or cables if they are faulty
- Replace or repair the voltage regulator if it is faulty
- Finding and replacing damaged cables or connectors that lead to the alternator
- Replace or repair a PCM that is faulty
How Serious is Error Code P0562?
The vehicle can stall if the voltage drops too low. It is therefore important to fix the problem immediately on the road in order to ensure both your safety and that of others.
