Stepper Motor Driver Pin Circuit Open
ECM controls the engine idle speed by regulating the IAC valve core shaft position. IAC valve's two internal coils are driven by the
stepper motors. idle air control valve's move is controlled by 4 circuits. ECM's driver controls idle air control valve two wires polarity
via these circuits. ECM commands the IAC valve stepper motor rotate clockwise or counterclockwise. IAC valve motor is connected
to the idle air control spool shaft through the driver screw. ECM sends electrical pulses to the IAC valve coils to allow the core shaft
stretch into or contract out of the throttle body channel. Through the core shaft, air flow increases, so the engine speed increases.
When the pivotal stretches, the air flow decreases, therefore the engine speed is reduced. If the engine control module detects the
engine speed is not in the expected range, the DTC codes will be set.
ECM harness connector EN01 terminals No. 21,22,35,36 are connected to IAC valve harness connector EN17 terminals B, A, C,
D.
