Q: What does code P1481 mean?

Fan Secondary Low with High Fans On. P1481 on Ford vehicles means the powertrain control module (PCM) commanded the high-speed cooling fan circuit on but continued to see a low or no-voltage condition on the secondary low-speed fan circuit. The PCM compares the expected state of the fan control circuits against the actual feedback and flags this code when the secondary low fan circuit does not respond as commanded.
