Code P1473 Ford Description
The P1473 Ford code indicates that there is a problem with the fan secondary circuit when the fans are supposed to be off. In a vehicle, the cooling fans are essential for regulating the engine temperature, especially during idle or low-speed driving conditions. When the engine reaches a certain temperature, the cooling fans should turn on to dissipate the heat. However, in this case, the code suggests that the secondary fan is running at a high speed even when it should be off. This can lead to inefficient cooling and potential overheating issues.
