Vacuum Leakage Inspection

1) Disconnect purge hose from intake manifold and tank pressure control valve hose from solenoid vacuum valve.
2) Turn EVAP canister purge valve ON (open) using SUZUKI scan tool or service wire.
3) Plug air valve hose end.
4) Connect vacuum pump gauge to disconnected tank pressure control valve hose end. And apply vacuum to tank pressure control valve.
5) Apply 3.5kPa (14.0 in Aq, 26.0 mmHg) to purge hose and seal it.
After 15sec., check to make sure that pressure is higher than 3.3kPa (13.6 in Aq, 24.5 mmHg).
If check result is satisfactory, fuel tank, purge line and component parts are in good condition.
If not proceed to next step (leak point check).

Leak Point Check
Locate pressure leaking point by using soap water or leak detector and repair.
