DTC P0449 Evaporative Emission (EVAP) Vent Solenoid Control Circuit.
Circuit Description
An ignition voltage is supplied to the evaporative emission (EVAP) canister vent solenoid valve. The control module grounds the EVAP canister vent solenoid valve control circuit to close the valve by means of an internal switch called a driver. The scan tool displays the commanded state of the EVAP canister vent solenoid valve as ON or OFF. The control module monitors the status of the driver. If the control module detects an incorrect voltage for the commanded state of the driver, this DTC sets.

check engine light ison,autozone says code is P0449 this is whattheir ticket says:

The PCM has determined that a malfunction exists in the electrical circuit for the vent valve/solenoid in the evaporative emission control system.

Definition:
EVAP (Evaporative Emission System) purge/vent solenoid circuit condition

Explanation:
The solenoids and system wiring are monitored for opens or shorts

Probable Causes
1- Purge or vent solenoids defective
2- Check connevtor and wiring
3- Fuel saturated vapor canister
4- Failed EVAP vent solenoid

I am sending you a little info on your problem.. Hope it helps.. Best of Luck..

2006 Chevrolet Colorado LT 2.8L, Vin 8, Eng Cfg L4 Customer Concern: Current Powertrain Control Module (PCM) code P0449. Tests/Procedures: 1. Inspect the evaporative vent solenoid, near the fuel tank and evaporative canister. Look for wire damage, corrosion.

2. Check voltage to the solenoid on the Orange wire. It should be battery voltage, backprobing. If not, check the voltage level on the CAN VENT fuse, #69 in the Underhood Bussed Electrical Center (UBEC).

3. Cycle the evaporative vent solenoid with a scan tool. The solenoid should click.

4. Backprobe the White wire, pin 22 of the blue PCM connector. The voltage on this wire should be battery voltage with the solenoid off and close to 0 volts with the solenoid on. Potential Causes: Evaporative Vent Solenoid
Solenoid Wiring
Tech Tips: The evaporative vent solenoid is attached to the side of the evaporative canister above the spare tire.

Hello. Your code indicates that your emission system is acting up. If you live in California, you might have a problem passing the next mandatory emmissions test. The PCM has determined that a malfunction exists in the electrical circuit for the vent valve/solenoid in the evaporative emission control system.
