

Depressing the accelerator pedal to a throttle valve opening angle of 50° or less.



Racing the engine to 4700 rpm or more.

d. Check that the VSV (for ACIS) is OFF (vent) under the following conditions below.



Releasing the accelerator pedal while under the VSV (for ACIS) OFF condition.



The engine is idling.

e. Connect the intelligent tester or Tech stream to the DLC3.

g. Install the V-bank cover.

3. INSPECT INTAKE AIR CONTROL VALVE

a. Inspect the diaphragm.

1. Using a vacuum pump, apply a vacuum of 27 kPa (200 mmHg, 7.85 in.Hg). Check that the

lever moves.

If the result is not as specified, replace the intake air surge tank.

4. CHECK AIR INDUCTION SYSTEM
