Q: What does code P1480 mean?

Fan Secondary Low with Low Fans On. P1480 on Ford vehicles means the powertrain control module (PCM) commanded the low-speed cooling fan circuit on, but the secondary fan monitor circuit reported a low or unexpected voltage condition. The PCM detects a mismatch between the fan command and the feedback signal from the secondary fan circuit, indicating a fault in the low-speed fan control or its monitoring circuit.
