P0560 and P0562 Generic DTC Codes
P0560 is talking about System Voltage too High
P0562 is talking about System Voltage too Low
It's a critical electrical issue that needs to be fixed asap
Take this P0560 and P0562 as issues with your house wiring
What happens when the voltage is too high?
Does it burn the bulbs and fry your electronic gadgets?
How about when the voltage is too low?
Does it effectively carry your electronic gadgets without frying them?
Same thing is applicable to your car
System too high means that the manufacturer's voltage threshold is above normal
Every car is 12 Volts rated, so when the PCM detects an unusual increase in voltage, it triggers the check engine or Malfunction light
This high voltage happens once the engine is turned on and can damage the fusebox, Wiring Harness and fry the ECM
It could be caused by using a higher fuse than normal, bad ECU fuse connection, overcharging alternator and overcharged battery
System too low means that the required voltage for your car is below threshold
Instead of 13.5 to 14.8V that should be supplied when engine is on, the voltage being supplied is way below the threshold
This issue can cause serious Malfunction to critical components of the car including the transmission, ABS, AC and Infortainment System
A bad positive battery terminal, bad battery, low charging alternator, corrosion and bad ground wires too
Most of the times, a malfunctioning battery regulator or ECM could be the cause
When you diagnose your car and see P0560 and P0562, it's best to follow the above guidelines to fix the issue before it cause critical damage to your car
