Code Definition

DTC P1474 indicates excessive current draw detected on Fan Control (FC) circuit when PCM grounds the circuit or with FC circuit not grounded by PCM, voltage is not detected on FC circuit (PCM expects to detect VPWR voltage coming through low speed FC relay coil to FC circuit). PCM monitors certain parameters such as engine coolant temperature, vehicle speed, A/C on/off status, and A/C pressure to determine engine cooling fan needs. PCM controls fan operation through FC outputs.
