ENGINE VACUUM CHECK
The engine vacuum that develops in the intake line is a good indica-
tor of the condition of the engine. The vacuum checking procedure
is as follows:
1) Warm up engine to normal operating temperature.
2) With engine stopped, disconnect MAP sensor hose from throttle
body and connect 3-way joint, hoses and special tool (vacuum
gauge and joint) between throttle body and MAP sensor hose
disconnected.
Special Tool

3) Run engine at specified idle speed (see Section 6E1), and read
vacuum gauge. Vacuum should be within following specifica-
tion.
Vacuum specification: 52.6 – 65.8 kPa (40 – 50 cm
4) After checking, connect MAP sensor hose to throttle body.
