How do you fix a P0449 evaporative emission control system vent valve solenoid circuit malfunction on a 2006 Chevy silverado?
Usually the problem with this code is an open vent solenoid valve. 12 volts is provided to solenoid and the pcm grounds the solenoid. When the pcm checks the circuit it is looking for 12 volts on the wire at pcm. The pink wire should have 12 volts and the white wire should be the ground circuit from the pcm. Ohm your vent valve it will probably be open.
How do you fix p0449?
Yeah, it almost has to be a bad vent solenoid, or a broken connection in the wiring to it. This code is saying that the PCM is not seeing the voltage change when it grounds the vent solenoid to activate it. Should have system voltage at one terminal with the ignition on, and a ground at the other terminal when the PCM commands the vent valve open.

Where is the evap system purge and vent solenoids located on a Buick LaSabre?
usually in front or on top of the gas tank. If you are getting a code like P0449 "Evap Vent Solenoid Control Circuit Malfunction" You could first check the wiring at the solenoid for corrsion, if OK change the valve. If the solenoid is on the top of the tank you have to drop the tank It is not by the tank. The purge valve is right on top of the odd #'d bank's intake. There are two vacuum lines running to it.
How do you fix OBDII code p0449 in a 2006 4-cylinder gmc canyon?
P0449 says that the PCM is not seeing the voltage potential it wants to see when the vent valve is off or commanded on. I would suspect it is the Evaporative Emissions (EVAP) Canister Vent Solenoid near or on top of the gas tank is bad. To make sure check the voltage at the pink wire. It should be around 12 volts. If it is low, it may be bad wiring or the PCM, but not likely. if you have 12 volts suspect the solenoid.
