DIAGNOSIS & TESTING

Leakage Inspection

Visually check that hoses, connections and gaskets have no cracks, leaks or damage.

Activated Charcoal Canister Inspection

1. Close port C and blow compressed air into port A, check 

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 

may cause engine to run improperly.

 Air suction caused by disconnections, looseness or cracks in intake system pipes related with throttle 

assembly will result in engine failure or abnormal operation. Replace parts as necessary.
