SYSTEM INSPECTION
NOTE:
Before inspection, check to make sure that gear shift lever is
in neutral position (with A/T model, selector lever in “P”
range) and that parking brake lever is pulled all the way up.
1) Warm up engine to normal operating temperature.
2) Disconnect vacuum hose (2) from “A” of EVAP canister purge
valve (1). With finger placed against hose disconnected, check
that vacuum is applied when engine is running at idle speed.
If it is not applied, check hoses for connection, leakage, clog
and deterioration.
Clean vacuum passage by blowing compressed air. Replace as
necessary.
3) If it is applied, connect vacuum hose to EVAP canister purge
valve.
