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.

2005 chevy 1500 silverado eng. light on ran code p0455 and p0449 how to fix the problem. and how much work it takes. thanks STEVE.


P0449 is the evap vent valve solenoid circuit malfuntion.
P0455 is an evap gross leak
Perhaps the gross leak code has to do with the vent valve. Find the vent valve. It should be near a rectangle evap canister. Maybe under the bed. The small vent line from the fuel tank will go to it. The solenoid is near the cansiter. With the key off the valve will be open. With the key on it should be closed. You may try disconnection the hose and blow through it with both key off and on and see if air will pass through. If the valve has died and is stuck open, that can be the huge leak.

If it is not the leak then a smoke machine should be used. Easier than searching the lines for bad o-rings, splits, or whatevers.

I HAVEA 2006 CHEVERLET SUBURBAN 1500, AND THE CHECK ENGINR LIGHT STEAYS ON. THE CODE IS P0449; WHAT IS THIS AND WHERE IS IT LOCATED AT.


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.

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 connector and wiring
3- fuel, saturated vapor canister
4- Failed EVAP vent solenoid

The vent solenoid is not working properly. The ecm driver could be defective, the wiring could be broken, or the vent solenoid just isn't working.
