Engine Vacuum Check
The engine vacuum that develops in the intake line is a good indi-
cator of the condition of the engine. The vacuum checking proce-
dure is as follows:
1) Warm up engine to normal operating temperature.
2) Stop engine and turn off the all electric switches.
3) Remove cap (1) from intake manifold.
4) Connect special tool (Vacuum gauge) to intake manifold.
Special tool

5) Run engine at specified idle speed and read vacuum gauge.
Vacuum should be within specification.
Vacuum specification (at sea level)
59 – 73 kPa (45 – 55 cm Hg, 17.7 – 21.6 in. Hg)
at specified idle speed
6) After checking, disconnect special tool (Vacuum gauge) from
intake manifold.
7) Install cap to intake manifold.NOTE:
After warming up engine, be sure to place transmission
gear shift lever in “Neutral” (shift selector lever to “P”
range for A/T model), and set parking brake and block
drive wheels.

Air Intake System
The main components of the air intake system are air cleaner (1), air cleaner outlet hose (2), throttle body (3),
idle air control valve (4) and intake manifold (5).
The air (by the amount corresponding to the throttle valve (6) opening and engine speed) is filtered by the air
cleaner (1), passes through the throttle body (3), is distributed by the intake manifold (5) and finally drawn into
each combustion chamber.
When the idle air control valve (4) is opened according to the signal from ECM, the air (7) bypasses the throttle
valve (6) through bypass passage and is finally drawn into the intake manifold (5).
