Checking the Coil Resistance
1. Disconnect the idle air control motor connector.
2. Measure resistance between terminal No. 2 and either

terminal No. 1 or terminal No. 3 of the connector at the idle
air control motor side.

Standard value: 28

− 33 ohms [at 20°C (68°F)]

3. If resistance is not within the standard value, replace the IAC

motor.

4. Measure the resistance between terminal No. 5 and either

terminal No. 6 or terminal No. 4 of the connector at the idle
air control motor side.

Standard value: 28

− 33 ohms [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 volts) to terminal No. 2 and the terminal
No. 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 No. 1 and terminal No. 4.

(2) Connect the negative terminal of the power supply to

terminal No. 3 and terminal No. 4.

(3) Connect the negative terminal of the power supply to

terminal No. 3 and terminal No. 6.

(4) Connect the negative terminal of the power supply to

terminal No. 1 and terminal No. 6.

(5) Connect the negative terminal of the power supply to

terminal No. 1 and terminal No. 4.

(6) Repeat the tests in sequence from (5) to (1) to test

opposite movement of the IAC.

>>A<< INJECTORS/FUEL PRESSURE REGULA-
TOR/HIGH-PRESSURE FUEL HOSE INSTALLATION

CAUTION

Do not let the engine oil get into the fuel rail will be dam-
aged.
1. Apply a drop of new engine oil to the O-ring.
2. Turn the injector. To the right and left to install to the fuel rail.

Repeat for fuel pressure regulator and fuel high-pressure
hose. Be careful not to damage the O-ring. After installing,
check that the item turns smoothly.

3. If it dose not turn smoothly, the O-ring may be trapped,

remove the item, re-install it into the fuel rail and check
again.

4. Tighten the fuel pressure regulator and fuel high-pressure

hose to the specified torque.

Tightening torque:

8.8

± 1.0 N⋅m (78 ± 9 in-lb) <Fuel pressure regulator>

4.9

± 1.0 N⋅m (44 ± 8 in-lb) <Fuel high-pressure hose>
