P0560
System Voltage Malfunction
DTC P0560, sometimes indicated as P056000 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the engine idling stability causing system voltage malfunction.
This code is set when the PCM detects that the voltage supplied to the powertrain is outside of the normal range. There are many possible causes for this code, including a defective battery, a bad alternator, a wiring problem, or a problem with the PCM.
If this code is stored, the first step is to check the battery voltage and test the alternator. If either of these components is defective, it will need to be replaced. If the problem is with the PCM, the module will need to be replaced.

2011 HYUNDAI SONATA with 174000. miles
We have had nothing but problems with our 2011 Hyundai Sonata. Less than a year ago our engine completely died while driving the vehicle. The dealership replaced the engine and since then we have had starting and electrical problems. When we went to pick up the car it didn't start right away and they told us we needed a new battery. We bought a new battery and about a week later it still wouldn't start on and off. Since we had the engine replaced, we have had to change the headlights and brake lights 4 times! We believe that when the engine died it caused an electrical issue. Fast forward about 9 months and now the car has 3 engine codes. P0017 P0014 and P0560. Crankshaft and camshaft position sensors and a system voltage malfunction. We will never buy a Hyundai again! They claim they totally replaced the engine but now i wonder if they salvaged old parts in the new engine and what exactly happened to the electrical system when the car shut off while driving.
