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.

and ”O2S B1 S2” to display the monitor.(d) Warm up the A/F sensor by running the engine at 2,500
rpm for approx. 2 minutes.(e) Keep the engine speed at 2,500 rpm and confirm that the
displays of the ”A/FS B1 S1” and ”A/FS B2 S1” are similarto the illustration on the left.
NOTICE:The illustration differs from the real display.HINT:The waveform of the A/F sensor is displayed only on the hand-held tester.(f) Confirm that the display of the ”O2S B1 S2” changes be-
tween 0V to 1V with the engine speed at 2,500 rpm.

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.

THROTTLE BODYON-VEHICLE INSPECTION1. CHECK FOR OPERATING SOUND(a) Turn the ignition switch to the ON position.(b) When turning the accelerator pedal position sensor lever,
listen to the running sound of the motor. Also, check thatthere is no friction sound.
If operation is not as specified, check the throttle control motor(see page DI-283 ), wiring and ECM.2. INSPECT THROTTLE POSITION SENSOR(a) Connect the hand-held tester to the DLC3.(b) Turn the ignition switch to the ON position.(c) When turning the accelerator pedal position sensor lever
to the full-open position, check the percentage of thethrottle valve opening angle (THROTTLE POS) of theCURRENT DATA.Standard percentage of the valve opening angle:60 % or more
If operation is not as specified, check the accelerator pedalposition sensor (see page DI-299 ), the wiring and the ECM.If not using a hand-held tester, measure the voltage betweenthe terminals (VTA1 - E2, VTA2 - E2) of the ECM connector(see page DI-34 ).3. INSPECT AIR ASSIST SYSTEM(a) Start the engine and check that the MIL does not illumi-
nate.(b) Let the engine warm up to the normal operating tempera-
ture.(c) Switch the A/C compressor from ON to OFF, and check
the idle speed.Idle speed (Transmission in neutral): 650 to 750 rpm
NOTICE:Perform inspection without an electrical load.
4. INSPECT THROTTLE BODY RESISTANCEUsing an ohmmeter, measure the resistance between the ter-minals.
Terminal No. Resistance
2 (M+) ⇔ 1 (M-) 0.3 to 100 Ω at 20 C (68 F)

VSV FOR EVAPORATIVEEMISSION (EVAP)INSPECTION1. REMOVE VSV2. INSPECT VSV(a) Inspect the VSV for an open circuit.
Using an ohmmeter, measure the resistance between theterminals.Resistance: 26 to 30 Ω at 20 C (68 F)
If the resistance is not as specified, 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 VSV operation.(1) Check that air does not flow from the ports.
(2) Apply battery voltage across the terminals.(3) Check that air flows from the ports.
If operation is not as specified, replace the VSV.3. REINSTALL VSV
