SENSOR INSPECTION
Disconnect the idle speed control motor position sensor
connector, and connect the special tool (test harness) to
the connector on idle speed control motor position sensor
side.
Measure the resistance between terminal @ (black clip of
special tool) and terminal 0 (white clip) of the idle speed
control motor position sensor connector.
Standard value: 4-6 kS2
(3) Disconnect the idle speed control motor connector.
(4) Connect a 6V DC power supply between terminals 0 and
(extend and retract) the idle speed control motor. Measure
the resistance between terminal @ (black clip of special
tool) and terminal 0 (red clip) of the idle speed control
motor position sensor connector.
Standard value: Smooth increase/decrease in ac-
Caution
Apply only a 6V DC or lower voltage. Application of
higher voltage could cause locking of the servo gears.
(5) If there is a deviation from the standard value, or if the
change is not smooth, replace the idle speed control motor
assembly.
