How to solve the P0562 trouble code?
2 Answers
This type of fault is usually caused by low ignition voltage. During inspection, confirm whether the input voltage of the ignition coil is 12V. It is recommended to have it checked by a professional. If the voltage is normal at 12V, then the ignition coil is internally damaged and needs to be replaced.
I've encountered the P0562 trouble code several times, which indicates low system voltage, usually pointing to battery or charging system issues. As an enthusiast who often repairs my own car, I first use a multimeter to check the battery voltage. If it reads below 12 volts when cold, it means insufficient voltage, possibly requiring charging or battery replacement. Next, I start the engine to test the alternator output, which should normally be between 13.5 to 14.5 volts. If it's too low, the alternator might be faulty. I also clean the battery terminals and connection points, as corrosion can affect contact; sometimes a blown fuse needs replacement too. These steps are manageable DIY tasks that save money and build skills. If the problem persists, it's best to visit a professional repair shop for deeper diagnostics with specialized tools. Regular maintenance shouldn't overlook battery condition—periodic checks help avoid roadside breakdowns.
