With CONSULT-II
1)
Start engine.
2)
Perform “PURG VOL CONT/V” in “ACTIVE TEST” mode with
CONSULT-II. Check that engine speed varies according to the
valve opening.
If OK, inspection end. If NG, go to following step.
3)
Check air passage continuity.

If NG, replace the EVAP canister purge volume control sole-
noid valve.
Without CONSULT-II
Check air passage continuity.
Condition
