Where is the carbon canister located?

The specific location of the automotive carbon canister is between the car engine and fuel tank. If removal is required, it must be performed by a professional repair shop. Do not attempt to remove the automotive carbon canister by yourself to avoid affecting the normal operation of the vehicle. Relevant information about automotive carbon canisters is as follows: 1. Replacement cycle: There is no fixed replacement interval for automotive carbon canisters, and vehicle manuals don't specify how often they should be replaced. As long as the carbon canister isn't damaged, replacement isn't necessary. 2. Working principle: When the engine starts, the solenoid valve between the activated carbon canister and intake manifold opens according to ECU instructions. At this time, gasoline vapor in the activated carbon canister will be drawn into the cylinder along with air under the vacuum pressure of the intake pipe to participate in combustion.
Last time I had my car repaired, I paid special attention to the location of the charcoal canister, which is specifically designed to absorb harmful gases evaporated from gasoline. Most vehicles hide it in one of two places: either tucked away in a corner of the engine bay, near the black box next to the engine control unit, or hidden underneath the car next to the fuel tank—some are secured with metal brackets, while others use plastic clips. If you drive a German car, you might even find it by lifting the trunk liner. I remember checking my old Volkswagen specifically, and the mechanic mentioned that this component shouldn’t be near the exhaust pipe, as excessive heat can deactivate the charcoal. Replacing it isn’t too difficult, but you’ll need to crawl under the car or remove some protective panels.
