P1479 2003 FORD F150 MeaningMonitors the High Fan Control (HFC) primary circuit output from the Powertrain Control Module (PCM). The test fails if the HFC output commanded on (grounded), excessive current draw is detected on the HFC circuit or, with the HFC circuit commanded off, 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).
