Hi,

The vent solenoid might be bad. You need to see If you are getting power to it. The computer provides a ground for the solenoid. You can test it by applying a power and a ground to the solenoid to see if it operates and open's and Close's. ( I am taking into V6 engine ).

SOURCE: i have a heater core leak on my 2000 chevy

You can bypass the heater core, you just wont have heat anymore. On the firewall of the truck, behind the engine, you will see 2 rubber heater hoses that go into the firewall. They attach to the heater core. Disconnect them and get a plastic connector, and connect the 2 hoses together with clamps to hold them down. This will stop coolant from going into the heater core, and no more leak.

SOURCE: We hooked up an OBD11 Auto Scanner to our 2005

P0449 has to do with the Evap System. The problem could be with wiring short circuit, Could be the EVAP canister purge valve or the ECM.
P0455 has to do with the evap system as well. Could be a leak in one of the hoses to the evap system so you need to check all lines to the evap system. There is also one hose that connects to the top of the tank that we have seen come loose. Could also be a intake leak or a problem with the Canister purge valve. You can fix these yourself somewhat. I would trace down all the lines first to see if anything has come loose under the vehicle to the Black plastic EVAP canisters. Without being able to check the valves you will probably have to take it to a shop to have them checked out or pay the price to replace the valves and gamble they are the problem.

That is laymans terms. That is why it is in your manual. You ,need to get up to speed ,on todays somewhat high tech vehicles.
Now you need to go to a shop that does EVAP testing, with a smoke machine,if necessary,or at least put a scanner on it ,and replace the vent valve solenoid,if bad.(again laymans part teminology,

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 have P0449 code on my 2008 Silverado. I believe its a vent solenoide. Wondering where its located and if its something I can fix or will i need a certified mechanic. Thanks.


It sounds like you need a new EVAP sensor, located by the gas tank. I have done this fix on a Chevy S-10 pickup before and it cost me less than $100, and a few hours in the garage.

2007 SILVERADO V6 EVAP PURGE SOLENOID


The evap purge solenoid is located on the intake manifold. The evap vent valve is located on the side of the fuel tank. If you have a P0449 or P0452 (I think) DTC, it will be the one on the tank that you need to replace.
