The activated carbon filter prevents the penetration of harmful fuel vapors from the fuel tank into the atmosphere. Fuel vapors accumulate in the activated carbon filter (absorber) and during engine operation are fed into the engine cylinders along with air.
The most common symptom of a malfunction in the EVAP system is a strong smell of gasoline in the engine compartment on pre-2001 vehicles, or under the vehicle on 2001+ vehicles. In this case, inspect the activated carbon filter.
A sign of clogging of the absorber can also be a decrease in the capacity of the fuel tank due to the vacuum that occurs in the tank due to improper operation of the system.
Pic. 2.39. Location of the activated carbon filter on vehicles up to 2001
On cars up to 2001, the filter is located in the left rear corner of the engine compartment (pic. 2.39).
Pic. 2.40. The location of the activated carbon filter on cars since 2001
On cars produced since 2001, the filter is located on the left side under the car, in front of the fuel tank (pic. 2.40).
Check the activated carbon filter housing and all hoses for damage.
