4. Also check harness for short to ground and short to power.

Is the inspection result normal?

YES

With CONSULT: GO TO 4.

YES

Without CONSULT: GO TO 5.

NO

Repair open circuit, short to ground or short to power in harness or connectors.

WITH CONSULT

1. Reconnect all harness connectors disconnected.
2. Start engine.
3. Perform "PURG VOL CONT/V" in "ACTIVE TEST" mode with CONSULT. Check that engine speed varies according to the valve opening.

Does engine speed vary according to the valve opening?

YES

NO

GO TO 5.

Refer to Component Inspection (EVAP Canister Purge Volume Control Solenoid Valve) .

Is the inspection result normal?

YES

INSPECTION END

NO

Replace EVAP canister purge volume control solenoid valve.
