Fault determination of idle speed stepper motor:
Before inspection, check whether the stepper
motor 4 PIN (black) connector and ECU plug-in
connector are loosened or improperly connected, and
then check the flashing of malfunction indicator light.
Inspection of stepper motor:
Measure the resistance between Pin A and Pin B and
that between Pin C and Pin D respectively with a
multimeter

can move between 0.44 and
2.00 mm.
