related pipes for water, fuel and other liquids. If liquids are present, check for disconnections and/or cracks in
the following: 1) the pipe from the air inlet port to the canister pump module; 2) the canister filter; and 3)
the fuel tank vent hose. If liquids are present in the canister interior, replace the canister and canister pump
module together.
Check for filter blockage in the canister. If the charcoal filter inside the canister is clogged, replace the
