After warming up engine, place transmission gear shift le-
ver in “Neutral” (shift selector lever to “P” range for A/T

2) With engine stopped, disconnect EVAP canister purge valve
hose from intake manifold and connect 3-way joint, hoses and
special tools (vacuum gauge and joint) between intake manifold
and vacuum hose disconnected.
