Code P1483 Description

The engine cooling fan is a variable speed fan. The Engine Control Module (ECM) controls the fan speed by sending a pulse width modulated signal to the cooling fan speed control module. The cooling fan control module varies the voltage drop across the engine cooling fan motor in relation to the pulse width modulated signal. The cooling fan speed is affected by many different conditions and can be adjusted from 10-90 percent duty cycle. Ninety percent is considered high fan speed. When multiple cooling speed requests are received, the ECM uses the highest cooling fan speed of all the requests. During normal fan ON operation, the control circuit voltage will be low and near battery voltage when the fan is OFF.

  The code P1483 for your 2019 Kia Sportage Hybrid refers to "Engine Cooling System Performance". It indicates an issue with the cooling system's efficiency, which could be caused by a malfunctioning thermostat, low coolant levels, a faulty water pump, or a clogged radiator. Check the coolant level and condition, and inspect the thermostat and cooling components for proper operation. Further diagnosis may be needed to resolve the issue.
