Checking the Operation Sound
1. Check that the engine coolant temperature is 20
_
C or
below.
NOTE
Disconnecting the engine coolant temperature sensor
connector and connecting the harness-side of the
connector to another engine coolant temperature sensor
that is at 20
_
C or below is also okay.
2. Check that the operation sound of the stepper motor
can be heard after the ignition is switched ON. (but without
starting the motor.)
3. If the operation sound cannot be heard, check the stepper
motor’s activation circuit.
If the circuit is normal, it is probable that there is a
malfunction of the stepper motor or of the engine control
unit.

1. Disconnect the idle speed control servo connector.
2. Measure the resistance between terminal 2 and either
terminal 1 or terminal 3 of the connector at the idle speed
