SOURCE: 2003 Chevy Silverado 1500 Error Codes

P0135 is a bad 02 sensor
P0442 is a evap problem
P0449 is a vent solenoid

i would check the vent solenoid first its a 4ws fuse under the hood in the fuse box make sure you have power to it you should have power at all times the ground comes from the pcm i think if you fix this everything else will work they are all computer controled

SOURCE: PO410, PO443, PO449 codes 1999 chevy malibu. what type of repair?

The first code is for the secondary air injection system. It could be as simple as a fuse or broken wire. It could also be the air pump. The second is the purge solenoid control circuit. Again it could be a wire or the solenoid. The third is also a EVAP code related to the vent valve, and may also be the wiring or the valve. Did all these codes set at the same time? If so you may be looking at a PCM problem. It is really hard to venture a guess at the cost without lnowing more. I advise you to use a good shop that you trust. It will take some special equiptment to properly diagnose these issues. Good Luck

SOURCE: where is my cabin air filter located on my 2008

You should get instructions on where to put the air filter when you purchase new ones.  I think that it is under the dash on the passenger side.  There should be a cover underneath the glove box with screws holding it in place.  This thing takes two air filters so Chevy can milk more money out of you.

My check engine light is on in my 2008 GMC SIERRA 1500 pickup with 5.3 V8 I have 2 fault codes, PO449 & PO455. I tried removing battery cable no help. Can anyone steer me in righ direction. Thanks


First check the tightness of your gas filler cap as this can cause the codes to set. To erase the codes you will need a scan tool or code reader . Check the wiring and connections for the EVAP vent solenoid . Fuel tank pressure sensor may be bad .

Where is the evap solenoid located on 2010 silverado? got the po449 code


P0449 is a code for the EVAP vent solenoid. You can find the vent solenoid on a support at the rear of the fuel tank. You have a electrical problem if you have only this code in the memory of the powertrain module. May be it's a broken wire(most of the time) or a
short to ground wire.

How can I replace a canister vent solenoid for a 2006 Chevy Tahoe code 449/300


Google the location & a picture & replace yourself

Has to be near the fuel tank

PO449 is the Evap Vent Solenoid

PO 300 is random cylinder misfires maybe from the
extra air, when the evap purge runs

2008 chevy cobalt engine light on


Your Po449 code means: Evaporative Emission (EVAP) Vent Solenoid Control Circuit. Check to see if anything on you EVAP system has gotten disconnected and make sure that none of your hoses have gotten old and bridle or have holes. If everything looks ok, you probably have to replaced the Vent Solenoid Valve, which is located on the EVAP canister.
