Q: What does code P1474 mean?

Low Fan Control Primary Circuit. P1474 on Ford vehicles means the powertrain control module (PCM) has detected a fault in the low-speed fan control primary circuit, which is the ground-side command wire for the low-speed cooling fan relay. The PCM monitors this circuit and sets the code when the voltage on the control wire does not match the commanded state, indicating an open, short, or excessive resistance in the primary circuit.
