Re: 2006 chevy colorado purge valve
Are you sure the purge valve is your problem? CEL code P0449 states Evaporative Emission Control System Vent Valve/Solenoid Circuit fault. The vent valve is located on the charcoal canister just in front of the spare tire underneeth the bed. I've removed the purge valve from my engine, just to check to make sure it works, and to do so I simply used a 12v drill battery to make sure the solenoid cycled. All was well there, so I'm leaning towards the vent valve on the canister. I believe its a different CEL code for a malfunction of the purge valve on the engine... perhaps someone knows which one.
Also, before you spend 185 bucks on one, I've read that you can buy the same part for a Silverado of the same year, and its 1/5th the cost, with the exception that you have to reuse the quick-disconnect hose that's attached to it.
