If you are referring to the canister that is part of the Evaporative Control System and is mounted either in the engine compartment or nearby the fuel tank, this canister is part of the emission controls that prevent gasoline vapors from escaping into the atmosphere. During non-run times, the charcoal absorbs the fumes and holds them until the next startup, when the canister is purged and the vapors burned.
In my experience the canister does not really age or lose its effectiveness unless it has been physically damaged or flooded by forcefully overfilling the fuel tank. Models with which I have worked do not typically recommend routine replacement, but it's always best to follow the manufacturer's guidelines especially as it pertains to emissions compliance in your region.
It must be on the charcoal canister. the charcoal canister should be located in the back of the car near the fuel tank.
The Evap canister (charcoal canister ) collects fuel vapour until it is drawn into the intake system when the evap solenoid is operated by the ECU
You would have a strong gas smell. If it's an older car, it may run badly because the charcoal can be sucked into the carberator. The only thing it really does is filter the air from the carb and tank.
It absorbs the gasoline vapors from the fuel tank while the car is parked. Once you start the car the vapors fromm the charcoal canister are purged back into your engine and burned.
it can, mine is bad and i will get smoke from time to time.
No damage to the car but you're releasing harmful emissions into the air.
The bottom of the canister is vented to the atmosphere.
The charcoal canister or vapor canister is underneath the car, just ahead of the gas tank and just behind the rear suspension. Looks like a large rectangular box with several rubber hoses running from it.
You can find the evap canister near Driver side rear wheel rear of gas tank underneath the car. Thanks
It usually happens when the sensor responsible for overfilling fails, gas starts to go in the charcoal vapor canister and contaminates it. It causes vacuum system (EVAP) to malfunction. You need to check the sensor or valve what ever you have in your car. You might have to replace the charcoal canister.
its under the car next to the gas tank, on the left side, if your are standing in front of the car. you'll have to remove your muffler to get at it .
