INSPECTION
1. CLEAN THROTTLE BODY
(a) Using a soft brush and carburetor cleaner, clean the cast
parts.
(b) Using compressed air, clean all the passages and aper-
tures.
NOTICE:
To prevent deterioration, do not clean the throttle position
sensor and IAC valve.
2. INSPECT THROTTLE VALVE
(a) Apply vacuum to the throttle opener.
(b) Check that there is no clearance between the throttle stop
screw and throttle lever when the throttle valve is fully
closed.
3. INSPECT THROTTLE POSITION SENSOR

INSPECTION
1. REMOVE VSV
2. INSPECT VSV FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the
terminals.
Resistance: 33 ± 39 W at 20°C (68°F)
If there is no continuity, replace the VSV.
3. INSPECT VSV FOR GROUND
Using an ohmmeter, check that there is no continuity between
each terminal and the body.
If there is continuity, replace the VSV.
4. INSPECT VSV OPERATION
(a) Check that air flows from ports E to G.
(b) Apply battery positive voltage across the terminals.
(c) Check that air flows from ports E to F.
If operation is not as specified, replace the VSV.
5. REINSTALL VSV

INSPECTION
1. DRAIN ENGINE COOLANT
2. REMOVE ECT SENSOR
(a) Disconnect the ECT sensor connector.
(b) Using a 19 mm deep socket wrench, remove the ECT
sensor and gasket.
3. 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.
4. REINSTALL ECT SENSOR
(a) Install a new gasket to the ECT sensor.
(b) Using a 19 mm deep socket, install the ECT sensor.
Torque: 20 N´m (200 kgf´cm, 14 ft´lbf)
(c) Connect the ECT sensor connector.
