that air flows from port B. If result is not as specified,
replace canister.
2. Close port C and blow compressed air into port B, check
that air flows from port A. If result is not as specified,
replace canister.
Fuel Tank Cap Assembly Inspection
1. Visually check that fuel tank cap assembly is not
deformed or damaged.
2. If result is not as specified, replace fuel tank cap
assembly.
CAUTION
Removal of engine oil dipstick, filler cap, PCV hose and other components or other problems in them
