What is the P0483 Fault code? What does it all mean?

If the powertrain control module (PCM), detects an excessive voltage signal on the electric cooling fan control circuit, a code P0483 will be generated.

The electric cooling fan cools the engine and controls the operation of the air conditioner system. It operates at a temperature that is set by the manufacturer. The PCM controls the electric cooling fan’s module. This module is typically mounted behind the radiator. Based on inputs from other sensors, the PCM turns on or off the cooling fan. The P0483 fault code will be set if the operating voltage of fan and the voltage ranges in the PCM’s RAM do not match.

The P0483 fault code can affect vehicles of all makes and models, including but not limited to: Fiat, Ford Fiat, Dodge, Jaguar Citroen Volvo, Chevrolet, Mazda Mercedes Benz, Subaru, Fiat, Fiat, Ford, Dodge, Ford, Dodge, Jaguar Citroen, Citroen, Volvo, Volvo, Ford, Dodge, Ford, Dodge, Jaguar Citroen, Volvo, Mercedes Benz, Mercedes Benz, Mercedes Benz, Mercedes Benz, Mercedes Benz, Mercedes Benz, Mercedes Benz, Mercedes Benz, Benz, Mercedes Benz, Mercedes Benz, Mercedes Benz, Mercedes Benz, Mercedes Benz, Mercedes Benz, Mercedes -Benz, Mercedes Benz, Mercedes Benz, Mercedes Benz, Fiat

What causes the P0483 Fault code?

P0483 means that there is a problem in the cooling fan. However, other components could also be causing this problem.

Code P0483 could be caused by:

  • – Defective cooling fan control module
  • – Defective cooling fan motor
  • – Defective cooling fan control relay
  • Blown fuse
  • – Damaged wires or loose connectors, open, or short circuit issues
  • – Temperature sensor for defective coolant
  • – Defective thermostat
  • – Defective circulation pump
  • – Defective PCM

 

What are the symptoms of the P0483 Fault Code?

These symptoms may be present in vehicles with code P0483.

  • – Illumination for check engine light
  • – Cooling fan running continuously or not at all
  • – Poor air conditioning system
  • – Engine overheating

 

How to Fix the P0483 Fault Code

The following repairs may be able to resolve the P0483 fault codes:

  • – Replacement of the cooling fan motor if necessary.
  • – Test and replacement of blower system fuses
  • – Making repairs and checking system relays and circuits
  • – Check the engine temperature. If the sensor is not up to manufacturer’s standards, replace it.
  • – Inspecting, testing and fixing all cables and connectors connected to the PCM.
  • – Replacing parts such as a defective thermostat or recirculation

 

How serious is the P0483 Fault code?

Depending on the reason for the fault, the severity of P0483 may vary. The problem can be serious if the cooling fan fails. It is okay if the problem isn’t electrical. Both cases require that the problem be addressed immediately. Motors that are not functioning properly may fail if they overheat. Driving in very hot weather can become uncomfortable if your air conditioner doesn’t work properly.
