ACOUSTIC CONTROL INDUCTION SYSTEM (ACIS)ON-VEHICLE INSPECTION1. INSPECT INTAKE AIR CONTROL FUNCTION

(a) Remove the V-bank cover.(b) Connect the hand-held tester to the DLC3.(c) Perform the ACTIVE TEST, then check that the actuator rod operates.(d) Start the engine.(e) Check that the VSV for ACIS is ON under the following conditions:

Depressing the accelerator pedal to 60% accelerator opening angle. Racing the engine above 4,700 rpm.

(f) Check that the VSV for ACIS is OFF under the following conditions: The engine idling. Release the accelerator pedal from the condition of step (e).

2. INSPECT INTAKE AIR CONTROL VALVE(a) Remove the V-bank cover.(b) Using a 3-way connector, connect the vacuum gauge to

the actuator hose.(c) Start the engine.(d) While the engine is idling, check that the vacuum gauge

needle momentarily fluctuates up to approx. 39.9 kPa(300 mmHg, 11.8 in.Hg). (The actuator rod is pulled out.)

(e) Rapidly and fully depress the accelerator pedal andcheck that the vacuum gauge needle points to 0 kPa (0mmHg, 0 in.Hg). (The actuator rod is returned.)

(f) Remove the vacuum gauge, and connect the vacuumhose to the actuator.

(g) Reinstall the V-bank cover.

3. INSPECT INTAKE AIR SURGE TANKInspect the diaphragm.

(1) Check that the lever moves when a vacuum of 26.6kPa (200 mmHg, 7.9 in.Hg) is applied with the MI-TYVAC (hand-held vacuum pump) on.

(2) Check that the vacuum of 26.6 kPa (200 mmHg, 7.9in.Hg) is sustained for 1 minute in the above state.

4. INSPECT VSV FOR ACIS(a) Inspect the VSV for on open circuit.

Using an ohmmeter, check that there is continuity be-tween each terminal.Resistance: 33 to 39 Ω at 20C (68F)

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

be taken.(1) Check that the battery terminals are properly con-

nected.(2) After repair work, check that the ignition coil termi-

nals and all other ignition system lines are recon-nected securely.

(3) When cleaning the engine compartment, be espe-cially careful to protect the electrical system fromwater.

(b) Precautions when handling the oxygen sensor and A/Fsensor.(1) Do not drop the oxygen sensor or A/F sensor or hit

them against another object.(2) Do not allow the sensor to come into contact with

water.5. IF VEHICLE IS EQUIPPED WITH MOBILE RADIO SYS-

TEM (HAM, CB, ETC.)If the vehicle is equipped with a mobile communication system,refer to the precaution in the IN section.6. AIR INDUCTION SYSTEM(a) Separation of the engine oil dipstick, oil filler cap, PCV

hose, etc. may cause the engine to be out of tune.(b) Disconnection, looseness or cracks in the parts of the air

induction system between the throttle body and cylinderhead will result in air suction and cause the engine to beout of tune.
