SENSOR INSPECTION
(1) Disconnect the idle speed control motor position sensor
connector.
(2) Measure the resistance between terminals
@ and 0.
Standard value: 4-6 k&2
I) Disconnect the idle speed control motor connector.
.) Connect DC 6V between terminals @ and @ of the idle
speed control motor connector, and then measure the re-
sistance between terminals
@ and @ of the idle speed
control motor position sensor connector when the idle
speed control motor is activated (caused to expand and
contract).
Standard value: Smooth increase/decrease in ac-
cordance with expansion and con-
traction of the idle speed control
motor plunger.
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.

OPERATION
l The volume of intake air during idling is reg-
ulated by the opening and closing of the throttle
valve, caused by expansion and contraction of
the servo plunger.
l The servo plunger expands or contracts in accordance with whether the DC motor (located
within the idle speed control motor) is driven in
the forward or reverse direction.
lThe DC motor is driven in either the forward or reverse direction according to the direction of
switching of the current flow of the motor-
activation
IC within the engine control module.
TROUBLESHOOTING HINTS
If there is unstable idling or engine stalling, etc., and
it is difficult to presume the cause of the problem,
switch ON the ignition switch and leave as is for 15
seconds or longer; then disconnect the servo
connector.
HARNESS INSPECTION
The cause of the problem can then be easily presumed by checking in this condition.Note that, if necessary, the engine speed adjusting
screw should be turned to adjust the engine rpm.
