COMPONENT INSPECTION
EVAP Canister Purge Volume Control Valve
With CONSULT
1. Disconnect EVAP canister purge volume control valve harness connector.




2. Check resistance between the following terminals.
terminal (2) and terminals (1), (3)
terminal (5) and terminals (4), (6)

Resistance: Approximately 30 ohms [At 25°C (77° F)]

3. Reconnect EVAP canister purge volume control valve harness connector.
4. Remove EVAP canister purge volume control valve from intake manifold collector and disconnect hoses from the valve. (Plug the purge hoses. The EVAP canister purge volume control valve harness connector should remain connected.)
5. Turn ignition switch "ON".
