P0484

DTC P0484, sometimes indicated as P048400 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 auxiliary emissions system causing cooling fan circuit over current.

A likely cause of this DTC is a defective cooling fan or a fan that is not properly seated in the fan shroud. If the fan is not properly seated, it can overheat and cause the DTC to set. A defective cooling fan can also overheat the engine and cause the DTC to set.
If the DTC is set because of a defective fan, the fan should be replaced. If the fan is not properly seated, the fan should be reseated.
