Symptom: The car every three Fuda five will appear automatically high-speed cooling fan operation, the specific phenomenon is that after turning on the ignition fan has been high-speed operation, if you turn off the ignition switch, the fan will be high-speed operation for some time before stopping. Fault diagnosis: The service technician first connects the diagnostic instrument to the engine system after receiving the vehicle and reads the fault code as: P0562 supply voltage is too low and below the lower limit; P0116 engine coolant temperature sensor 1 is not trusted signal. According to the meaning of the fault code to analyze, P0562 should belong to the fan often lead to the battery
