3. If the sensor is defective, replace the heated oxygen sensor.
NOTE: For removal and installation of the heated oxygen
sensor, refer to GROUP 15, Exhaust Pipe and Main Muffler

Measurement of Resistance between Terminals
1. Disconnect the injector intermediate connector.
2. Measure resistance between terminals.
Standard value: 13
−
16
Ω
[at 20
°
C (68
°
F)]
3. If not within specification, replace the injector.
4. Install the injector connector
Checking operation sound
Using a stethoscope or long blade screwdriver, check the
operation sound ("tick-tick-tick") of injectors during idling or
during cranking. Check that as the engine speed increases, the
frequency of the operating sound also increases.
1. If the injector you are checking is not operating, you may
hear the operating sound of the other injectors.
2. If no operating sound is heard from the injector that is being
checked, check the injector drive circuit. If there is nothing
wrong with the circuit, a defective injector or powertrain
control module (PCM) is suspected.

NOTE: If necessary, you can disconnect the engine coolant
temperature sensor connector and connect the harness-side
of the connector to another engine coolant temperature
sensor that is at 20
°
C (68
°
F) or below.
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
engine control module (ECM) <M/T> or powertrain control
module (PCM) <A/T>.
Checking the Coil Resistance
1. Disconnect the idle air control motor connector.
2. Measure resistance between terminal 2 and either terminal
1 or terminal 3 of the connector at the idle air control motor
side.
Standard value: 28
−
33
Ω
[at 20
°
C (68
°
F)]
3. If resistance is not within the standard value, replace the IAC
motor.
4. Measure the resistance between terminal 5 and either
terminal 6 or terminal 4 of the connector at the idle air
control motor side.
Standard value: 28
−
33
Ω
[at 20
°
C (68
°
F)]
5. If resistance is not within the standard value, replace the IAC
motor.
<Operation Check>
1. Remove the throttle body.
2. Remove the idle air control motor.
3. Connect special tool MB991709 to the idle air control motor
connector.
4. Connect the positive (+) terminal of a power supply
(approximately 6 V) to terminal 2 and the terminal 5.
5. Connect the negative (-) terminal of the power supply to
each clip as described in the following steps. Then check
whether or not the stepper motor vibrates slightly as it
operates.
(1) Connect the negative terminal of the power supply to
terminal 1 and terminal 4.
(2) Connect the negative terminal of the power supply to
terminal 3 and terminal 4.
(3) Connect the negative terminal of the power supply to
terminal 3 and terminal 6.

(4) Connect the negative terminal of the power supply to
terminal 1 and terminal 6.
(5) Connect the negative terminal of the power supply to
terminal 1 and terminal 4.
(6) Repeat the tests in sequence from (5) to (1) to test
opposite movement of the IAC.
6. If vibration is detected during the test, the stepper motor can
be considered to be normal.
