What does Error Code P0562 mean?

Critical Issue
DTC Code P0562 indicates a Charging System Voltage Low condition, where the Engine Control Module (ECM) detects that the electrical system voltage level is below the required range, potentially affecting the ECM's ability to store critical data.

What are the symptoms of Error Code P0562?

  • Engine Light ON: The 'Check Engine' or 'Service Engine Soon' warning light illuminates, indicating a potential issue with the charging system.
  • Slow Engine Start: The engine may crank slowly or take longer to start due to insufficient voltage supply from the charging system.
  • Low Battery Power: The battery may not hold a charge effectively, leading to reduced power availability for starting and operating the vehicle's electrical systems.

What causes Error Code P0562?

  • The battery may not be holding a sufficient charge, which can lead to low system voltage.
  • A defective battery can cause inadequate voltage supply to the vehicle's electrical system.
  • A loose or missing alternator drive belt can prevent the alternator from charging the battery effectively.
  • A faulty alternator may not generate enough voltage to maintain the battery's charge and power the vehicle's electrical components.
  • An open or short in the system voltage circuit can disrupt the flow of electricity, leading to low voltage readings.

How to fix Error Code P0562?

  • Initial Battery Check: Begin by recharging or replacing the battery as low voltage can trigger DTC P0562. Ensure the battery terminals are clean and securely connected.
  • Inspect Alternator Output: Measure the alternator output voltage using a multimeter. It should be between 13.5 and 14.5 volts with the engine running. If not, the alternator may be faulty.
  • Check Alternator Belt: Inspect the alternator belt for wear or damage. Ensure it is properly tensioned as a loose or damaged belt can affect charging efficiency.
  • Examine Wiring and Connections: Inspect the wiring and connections between the alternator, battery, and voltage regulator for any signs of corrosion, damage, or loose connections.
  • Test Voltage Regulator: Check the voltage regulator for proper operation. A faulty regulator can cause incorrect voltage levels, leading to a P0562 code.
  • Scan for Additional Codes: Use an OBD-II scanner to check for any additional codes that may indicate related issues affecting the charging system.
