That is an EVAP code. its a vent control code. you can manually test it by powering it up if you know where its at. i cant remember exaclty where its at off the top of my head but its only 2 wires. using a volt meter you want to make sure power is getting to it, but you cannot activate it without dealer scan tool.hmmm if you can figure out which is ground and power when you give it 12 volts it should click. meaning your vent solenoid works and you have wiring problems or its leaking.
EVAP problems are hard to finde with out scanners. you can change the vent solenoid and hope it fixes it. but a code points you to the direction of a problem. hopefull its not wiring problems. in the northern states with snow. ice can pull out wires and also get clogged in the vent solenoid and lock it up. its either wiring or bad or a leaking solenoid. check condition of wires. if they look good try a vent soleniod.
if that doesnt fix it after a engine light reset and 2 weeks or so. then goto dealer. you need to reset it after repair. light will not go off on its own.GOOD LUCK

This code indicates the EVAP vent valve is the problem.It calls for a circut check. Recommend checking vent valve for dirt. Testing this system requires GM tools. Replacing vent valve without testing is try and see. Does this help? Moe
EVAP Vent Control Solenoid Circuit Malfunction
Possible Causes:
Vent solenoid circuit open, shorted to ground or to power (B+).Vent control solenoid is damaged or has failed..PCM has failed.TSB 00-060 (7/00) contains information related to this code.Trouble Code: P0455
EVAP System Gross Leak (0.080") Detected
Possible Causes:
.EVAP control system pressure sensor is damaged or has failed.EVAP purge solenoid or canister vacuum line loose or off.EVAP purge solenoid is damaged or has failed.EVAP emission canister is dirty, restricted or full of water.EVAP canister vent control valve is damaged or has failed.Fuel tank cap loose, missing or it is the wrong part number.Fuel tank temperature sensor is damaged or has failed.Fuel tank vacuum relief valve is damaged or has failed.Large leak in the EVAP canister or in the fuel tank area.ORVR system is damaged or has a large leak in a component.Refueling control valve is damaged or has failed.Vacuum hose leaking between intake manifold and Purge valve.Here are the codes,take part back and get refund.
Most likely is a bad EVAP purge valve. But check below list.
This indicates that a part of the EVAP
control system is no longer functioning correctly. The EVAP system consists of
many parts, including (but not limited to) the gas cap, fuel lines, carbon
canister, purge valve, and other hoses. The (EVAP) emission control system
prevents the escape of fuel vapors from a vehicle's fuel
system. Fuel vapors are routed by hoses to a charcoal canister for storage.
Later, when the engine is running a purge control valve opens allowing intake
vacuum to siphon the fuel vapors into the engine.
EVAP emission canister purge is controlled
by a valve which allows engine vacuum to pull stored fuel vapors from fuel tank
into the engine to be burned, rather than be vented to atmosphere. A vacuum
switch is used to detect when flow exists. If the PCM commands purge and sees
that the switch is closed (indicating no detected purge flow) P0441 is set.

Symptoms
Likely, no symptoms will be discernible to
the driver, other than the illuminated Check Engine Light.
Causes
A code P0441 could mean one or more of the
following has happened:
With a P0441 OBD-II trouble code, diagnosis
can be tricky at times. Here are some things to try:
