on top of the canister purge can , next to the solenoid of same purpose

HERE'S WHAT IT LOOK'S LIKE.Mounted near evaporative canister. http://www.autozone.com/engine-management/canister-vent-valve-solenoid/dorman-canister-vent-valve-solenoid/kia/sorento-2wd/2004/6-cylinders-3-3-5l-mfi-dohc/970779_548862_0

possibly next to the evaporator canister they are usually there on most cars you should see a little round canister with a plug for electric and rubber hose 's on it like a tee fitting the evaporator canister is a black charcoal containing box with hose's also coming in & out of it the vent solenoid is about the size of a aspirin bottle and the evaporator canister is about the size of a nestle quick container and it should be black or grey

This Pinpoint Test is intended to diagnose the following:

• Canister vent (CV) solenoid (9F945) (electrical concern only)
• Fuel filler cap (9030)
• Fuel tank pressure (FTP) sensor (9C052)
• EVAP canister tube (fuel tank to EVAP canister)(9A228)
• Fuel canister purge outlet tube (EVAP canister to EVAP canister purge valve) (9D661)
• EVAP return tube (EVAP canister purge valve to intake manifold) (9G271)
• EVAP canister purge valve (9C915)
• Vacuum source line (input port vacuum to intake manifold)
• Harness circuits: CV, FLI, FTP, EVAP Canister Purge Valve, SIG RTN, vehicle power (VPWR), reference voltage (VREF) and power ground (PWR GND)
• Powertrain control module (PCM) (12A650)

This Pinpoint Test is used as an assistance in diagnosing the following EVAP components:

• EVAP canister and bracket assembly (9E857)
  • EVAP canister sleeve assembly (fitting)(9D925)
  • Canister vent (CV) solenoid - hose assembly (9F976 or 9K318)
  • EVAP canister (9D653)
  • Canister vent (CV) solenoid (9F945)(mechanical concern only)
• Fill limit valve assembly (9A086)
• Fuel filler pipe flapper valve (9B085)
• Fuel filler pipe check valve (9189), assembly (9285)
• Fuel tank filler pipe (9034)
• Fuel tank assembly (with fuel vapor vent valve) (9K007)
• Fuel tank assembly (without fuel vapor vent valve) (9002)
• Fuel vapor control valve (9B190)
• Fuel vapor vent valve (9B593)
• Liquid/vapor fuel discriminator (9G332)
• On-board refueling vapor recovery (ORVR) T - connector assembly (9S314)

This Code is for the Evaporator vent control circuit. First, try to tighten the fuel cap. If you take the car to Autozone, Oreillys, or Advance they will scan it for free. They can also clear the problem codes.

The Evaporator vent circuit is the wiring or Solenoid which makes the gas fumes flow into the canister box. Your Solenoid could be burned out or the connector could have corrosion. When you see the replacement part at an autoparts store, you will know what to look for. The solenoid is either near or on the canister box. Sometimes overfilling the gas tank can allow raw fuel to travel into this area by mistake. It is meant to control fumes and not solids.

In rare cases the vent lines may have holes in them and may contribute to this warning. A "smoke machine" would be necessary to find the holes and you would need to find a Repair shop with such a machine. Try the easy stuff first and it will likely solve your problem.

More than likely the evaporator vent valve.
