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.
NOTE:
After warming up engine, place transmission gear shift le-
ver in “Neutral” (shift selector lever to “P” range for A/T
model), and set parking brake and block drive wheels.
2) With engine stopped, disconnect EVAP canister purge valve
hose (1) from intake manifold (2) and connect 3-way joint,
hoses and special tool (vacuum gauge and joint) between in-
take manifold and EVAP canister purge valve hose discon-
nected.

3) Run engine at specified idle speed (refer to Section 6E1), and
read vacuum gauge. Vacuum should be within following specifi-
cation.
Vacuum specification: 52.6 – 65.8 kPa (40 – 50 cm
.
Hg,
(at sea level) 15.7 – 19.7 in
.
Hg) at specified
idling speed
4) After checking, connect vacuum hose.
OIL PRESSURE CHECK
NOTE:
Prior to checking oil pressure, check the followings.
Oil level in oil pan.
If oil level is low, add oil up to Full level hole on oil level
gauge.
Oil quality.
