Code P0481 2011 Ford Fusion Description

Monitors the High Fan Control (HFC) primary circuit output from the Powertrain Control Module (PCM). The test fails, when the HFC output is commanded on (grounded) and excessive current draw is detected on the HFC circuit; or when the HFC circuit is commanded off and voltage is not detected on the HFC circuit (the PCM expects to detect VPWR voltage through the high speed FC relay coil to the HFC circuit).
