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 code p1451 on a ford cargo van?
Technical DescriptionEVAP Control System Canister Vent Solenoid Circuit Malfunction What does that mean?The EVAP system monitors the canister vent (CV) solenoid circuit for an electrical failure. The test fails when the signal moves outside the minimum or maximum allowable calibrated parameters for a specified canister vent duty cycle by PCM command. SymptomsYou will likely not notice any drivability problems. CausesA code P1451 may mean that one or more of the following has happened: VPWR circuit openDamaged canister vent solenoidCanister vent solenoid circuit open or shorted to ground, power, etc.Damaged Powertrain Control Module (PCM)Possible SolutionsVerify canister vent solenoid - To verify normal functioning, monitor the EVAP canister vent solenoid signal PID EVAPCV and the signal voltage (PCM control side). With the valve open, EVAPCV indicates 0% duty cycle and a voltage approximately equal to battery voltage. When the valve is commanded fully closed, EVAPCV indicates 100% duty cycle, and a minimum voltage drop of 4 volts is normal. Output test mode may be used to switch output on/off to verify function.Replace canister vent solenoid
