The P0560 trouble code indicates a malfunction in the vehicle’s electrical system voltage. The powertrain control module (PCM) monitors the voltage level in the system, and if it falls outside the predetermined range, this code is triggered.
System Voltage Malfunction
Code symptoms P0560.
1. Illumination of the Check Engine Light.
2. Battery warning light may illuminate on the dashboard.
3. Fluctuations in vehicle electrical system performance.
4. Possible difficulty starting the vehicle.
5. Dimming of lights or other electrical accessories.
This code is common in brands such as:: Chevrolet, Renault, Ford, Toyota, Nissan, Mercedes Benz, Honda.
Causes of the code P0560.
1. Weak or failing battery.
2. Faulty alternator or charging system.
3. Corroded or loose battery terminals or wiring.
4. Issues with the voltage regulator.
5. Faulty PCM.
Code Solutions P0560.
1. Check the battery voltage with a multimeter to ensure it is within the manufacturer’s specified range. If the voltage is low, the battery may need to be charged or replaced.
2. Inspect the alternator and charging system components, including the alternator, voltage regulator, and associated wiring, for any signs of damage or wear. Replace any faulty components as needed.
3. Clean and tighten the battery terminals and connections to ensure a secure electrical connection. Corroded terminals can lead to voltage fluctuations.
4. Test the voltage regulator to ensure it is regulating voltage correctly. Replace if necessary.
5. If no issues are found with the battery, alternator, or charging system, the PCM may be at fault. Further diagnostic testing may be needed to confirm this, and if necessary, the PCM should be replaced or reprogrammed.
