Chevrolet Malibu Vapor Canister
Chevrolet Malibu Vapor Canister Troubleshooting Tips
Did you know that your Chevrolet Malibu's vapor canister has been keeping you and your passengers safe from pollutants caused by fuel? For the longest time, it has been absorbing the fuel vapors to keep it from being released in the atmosphere that could harm the environment. When it gets saturated or its lines develop cuts or cracks, you and your passengers are at risk of inhaling harmful fumes that are dangerous to your health. Before this happens, follow these useful troubleshooting tips on how to diagnose some problems that could be related to a defective Chevrolet Malibu vapor canister:
So you have probably smelled it; the stench of fuel that you should never smell. The fuel fumes that the vapor canister has been absorbing have leaked. When this happens, you can start your troubleshooting by removing all of the lines from the canister and start your vehicle. If there is any fuel coming through the lines, then it is messed up. Check for any crossed lines or cuts in the fuel vapor hoses or tubes, but if there is no fuel coming from any of the lines, then your vapor canister must be full of fuel. You can either clean the vapor canister if it is relatively new, or replace it if it is already old.
Failed emission test
If you have failed in the emission test several times now, but there seems to be no problem with your exhaust system, then there could be a problem with your vapor canister. It could either be leaking the gas fumes that it should be absorbing, or it is already oversaturated. To confirm this, check if there is any puddle of gas near the area where the canister is located. You can also stick your finger in the end of the hose and check if there is wetness. If there is, then your canister is already oversaturated. A quick fix could be done by cleaning the canister using a carburetor cleaner. Put some into the vent pipe and shake the canister to remove the gas vapor buildup. Drain it afterwards.
