INSPECT INTAKE AIR CONTROL VALVE
(a) Using a 3±way connector, connect vacuum gauge to the
actuator hose.
(b) Start the engine.
(c) While the engine is idling, check that the vacuum gauge
needle does not move.
(d) Rapidly depress the accelerator pedal to fully open posi-
tion and check that the vacuum gauge needle momentari-
ly fluctuates up to approx. 26.7 kPa (200 mmHg, 7.9
in.Hg). (The actuator rod is pulled out.)

REMOVAL
1. DISCONNECT ACTUATOR VACUUM HOSE
2. DISCONNECT DLC1 FROM DLC1 BRACKET
3. REMOVE INTAKE AIR CONTROL VALVE
(a) Remove the 4 nuts and DLC1 bracket, and disconnect the
ground strap and cable.
(b) Remove the intake air control valve by prying a screwdriv-
er between the intake air control valve and air intake
chamber.
(c) Remove the gasket.

INSTALLATION
1. INSTALL INTAKE AIR CONTROL VALVE
(a) Install a new gasket to the air intake chamber.
(b) Apply a light coat of engine oil to the rubber portions.
(c) Apply seal packing to the positions of the intake air control
valve shown in the illustration.
Seal packing: Part No. 08826±00080 or equivalent
(d) Install the intake air control valve, DLC1 bracket, ground
strap and cable with the 4 nuts.
Torque: 14.5 N´m (145 kgf´cm, 10 ft´lbf)

INSPECTION
1. REMOVE V±BANK COVER, HIGH±TENSION CORD
COVER AND EMISSION CONTROL VALVE SET
2. REMOVE VSV
(a) Disconnect the 3 vacuum hoses from the VSV.
(b) Remove the screw and VSV.
3. INSPECT VSV FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the
terminals.
Resistance: 27 ± 33 W at 20°C (68°F)
If there is no continuity, replace the VSV.
4. 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.
5. INSPECT VSV OPERATION
(a) Check that air flows from port E to port G.
(b) Apply battery positive voltage across the terminals.
(c) Check that air flows from port E to port F.
If operation is not as specified, replace the VSV.
6. REINSTALL VSV
(a) Install the VSV with the screw.
(b) Connect the 3 vacuum hoses to the VSV.
7. REINSTALL EMISSION CONTROL VALVE SET
8. REINSTALL HIGH±TENSION CORD COVER
9. REINSTALL V±BANK COVER
