INSPECTION

1.

REMOVE VSV

2.

INSPECT VSV

(a)

Inspect the VSV for open circuit.
Using an ohmmeter, check that there is continuity be-
tween the terminals.
Resistance: 30 to 34 

Ω

 at 20

°

C (68

°

F)

If there is no continuity, replace the VSV.

(b)

Inspect the VSV for ground.
Using an ohmmeter, check that there is no continuity be-
tween each terminal and the body.

If there is continuity, replace the VSV.

(c)

Inspect the VSV operation.
(1)

Check that air dose not flow from port.

(2)

Apply battery positive voltage across the terminals.

(3)

Check that air flows from port.

If operation is not as specified, replace the VSV.

2.

REMOVE THROTTLE BODY COVER

3.

REMOVE INTAKE AIR CONNECTOR

4.

DISCONNECT THROTTLE BODY FROM INTAKE MAN-
IFOLDS

Remove the nut and 3 bolts, and disconnect the throttle body
from the intake manifold.

5.

REMOVE ECT SENSOR

(a)

Disconnect the ECT sensor connector.

(b)

Remove the ECT sensor and gasket.

6.

INSPECT ECT SENSOR

Using an ohmmeter, measure the resistance between the ter-
minals.

Resistance: Refer to the graph

If the resistance is not as specified, replace the ECT sensor.
7.

REINSTALL ECT SENSOR

(a)

Install a new gasket and the ECT sensor.
Torque: 19.6 N·m (200 kgf·cm, 14 ft·lbf)

(b)

Connect the ECT sensor connector.

8.

REINSTALL THROTTLE BODY TO INTAKE MAN-
IFOLDS

Install a new gasket and the throttle body with the 2 bolts and
2 nuts.

Torque: 20 N·m (204 kgf·cm, 15 ft·lbf)
