Each time power is applied to outdoor unit the EXV-VI will operate to a known position as the valve does not have the capability to feedback actual position. The PCM software must know the starting point and then counts as the EXV stepper motor is pulsed. At the end of each cycle the valve will close to help maintain pressure differential and optimize cyclic efficiency. HP units will not operate if this fault is active because the valve position at time of failure is unknown.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This code occurs when the PCM determines the resistance of the stepper motor coil circuit is above the maximum value to properly function. Inspection of the wire harness and plug should be performed, as well as using a multimeter to confirm &#8220;open&#8221; continuity between pins. If nothing is found, replace coil and harness assembly.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n<p class=\"has-small-font-size wp-block-paragraph\"><em>Source:
