First, you need to use a 90-degree pick to disengage the lower filter cover clips, insert a flat-bladed tool between the filter cover and canister, and push up to disengage the upper clips. Then, please remove and discard the evaporative emission (EVAP) canister filter cover and the EVAP canister filter. Finally, you should clean the inside of the EVAP canister filter housing with a clean shop towel.
