2000 Accent GL Sedan 1.5. Canister Close Valve not closing.

Customer Question

2000 Accent GL Sedan 1.5. Canister Close Valve not closing. Code PO442 present. 0 volts present key on\off. I ascertained wiring diagram online without inclusion of this circuit. I realize CCV should be energized with key off to prevent fuel vapor/pressure to escape. Is the CCV controlled via a relay/fuse/fusible link/ECU? I am in need of electrical diagram for this circuit or flow chart. Note: purge control solenoid is operational. Thanks. Tom D.
