Code P1473 Lincoln Description

The P1473 diagnostic trouble code (DTC) in a Lincoln vehicle indicates that the secondary cooling fan is operating at a higher than expected speed when the fans are supposed to be off. This issue typically occurs when the vehicle's engine is not running and the cooling fans should be idle. The secondary cooling fan is responsible for helping regulate the temperature of the engine and preventing it from overheating. When this fan operates at a high speed without the engine running, it can lead to increased power consumption, potential damage to the fan motor, and decreased fuel efficiency.
