On the 2010 Chevy Camaro V6, that vent solenoid is on top of the rear cross member. You might be able to squeeze a VERY small hand in there, but the regular service procedure is to drop the cross member down. Sucks, as I just had to replace the same valve.

The EVAP vent solenoid is located by the gas tank and above the rear axle. The dealership will drop the rear assembly and replace the EVAP vent solenoid, then do an alignment. The cost is close to $1,000!

SOURCE: P0449 Evaporative Emission Control System Vent

While looking for the location of the vent/solenoid for you, I came across a blog that said this error can be caused by a loose or faulty gas cap. You may want to look at that first and possibly solving the problem. Replace the cap, get autoparts store to reset the code and see what happens.

SOURCE: Getting codes P0455 and P0449. From what I read,

The vent solenoid valve has been redesigned to correct the problem you are having. I would recommend purchasing the dealer component.
I am not aware of any aftermarket parts suppliers.

SOURCE: code p0449.

GM uses an EVAP solenoid that is located under most vehicles near the gas tank and connects to the charcoal filter can. Codes can be set and will drive you crazy trying to figure out if you have a bad gas cap, broke lines---this is where they try to get you to do a smoke test, or you just think the vehicle is no good! Relax, it is usually an easy fix and one GM has known about for years but continues to make easy money off people who cannot do basic maintenance. Now one code that comes up is usually P0449, along with maybe a warning to check the gas cap to see if it is on tight! GM will gladly read this code out for you for around $98.00 and then fix it for another around $100.00 which includes the EVAP part which if you buy at their parts dept. will cost you $32.00 and my dealership parts man told me they sell one a day! It is easy money for them and obviously a defective part they keep using for the last 10 or 15 years but hey, its money in their pocket. Here is how to fix it with ONE single common screwdriver! Get under the vehicle after putting on the parking brake. The EVAP solenoid is easy to spot near the gas tank and it has one electric connector which disconnects by releasing the plastic clip and pulling the connector out. It also has ONE air line connected which goes to the charcoal cannister which also can be removed with the one screwdriver. The whole EVAP solenoid and air can can be removed with the screwdriver which makes it easier to unplug the electric and air line. Get a replacement from the dealer as they certainly are familiar with this part as they sell LOTS of them. Then just go under and plug the new one in and the problem is solved. Now if you do not have a tool to reset the codes, try the local parts places as most of them will do a reset for you.

2001 Buick LeSabre 3.8 V6 Code P0449 , what needs Replaced?? Car will Not Start. Stalls and Dies. Supposed Fix: Vapor Canister Vent Solenoid; Exact Location & Replacement Procedure??


Malfunction The evaporative control (EVAP) system captures any raw fuel evaporating from the fuel storage system (e.g. the fuel tank, filler neck, and fuel cap). Under precise operating conditions-dictated by engine temperature, speed, and load-the EVAP system stores and purges these captured fuel vapors back into the combustion process. The carbon canister, which stores the raw fuel vapors, utilizes a vent valve that allows fresh air to enter the EVAP system. This displaces the fuel vapor as it's purged into the combustion process. Code P0449 indicates that the evaporative control (EVAP) system vent valve solenoid is malfunctioning. This can be caused by either too little or too much electrical resistance or a mechanical problem with the vent valve itself. P0449 Symptoms
  • Check Engine Light will illuminate
  • In most cases, there are no adverse conditions noticed by the driver
  • In some cases, there may be a noticeable fuel odor caused by the release of fuel vapors
Common Problems That Trigger the P0449 Code
  • Missing fuel cap
  • Defective Evaporative Vent Valve
  • Defective or damaged fuel cap
  • Distorted, damaged or cracked Fuel Tank Filler Neck
  • Torn or punctured Evaporative system hose(s)
  • Defective Fuel Tank Sending Unit gasket or seal
  • Split or damaged Carbon Canister
  • Defective or damaged fuel tank
Common Misdiagnoses
  • Fuel cap
  • Evaporative Purge Valve
  • Evaporative Vent Valve
Polluting Gases Expelled
  • HCs (Hydrocarbons): Unburned droplets of raw fuel that smell, affect breathing, and contribute to smog

Engine code 499


I am Assuming that it is a "P" Code so the code is actually P0449.

P0449 is evaporative emission control system - vent valve / solenoid circuit

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 ).
