P0560: System Voltage Malfunction
Can you still drive? Drive cautiously to a repair shop. If the alternator is failing, the battery will drain and the vehicle will eventually stall. Minimize electrical accessory use.
What Does P0560 Mean?
Code P0560 indicates that the PCM has detected an abnormal system voltage level that does not match expected charging system output. The PCM monitors battery voltage to manage fuel injection timing, idle speed, and other parameters. Voltage outside the normal 13.5-14.5 volt range while running triggers this code.
Need to read your codes?
An OBD-II scanner lets you read and clear diagnostic trouble codes from your vehicle's computer. Most scanners work with any car made after 1996.
