Accent GT Coupe L4-1495cc 1.5L DOHC MFI (1997)
Catalytic Converter: Description and Operation
THREE-WAY CATALYTIC CONVERTER (TWC)
CATALYTIC CONVERTER INSPECTION
Inspect for damage, cracking or deterioration. Replace if faulty.
CAUTION: The catalytic converters require the use of unleaded gasoline only. Leaded gasoline will destroy the effectiveness of the catalysts as
an emission control device.
Under normal operating conditions, the catalytic converters will not require maintenance. However, it is important to keep the engine properly
tuned. Engine misfiring may cause overheating of the catalysts. This may cause heat damage to the converters or vehicle components. This
situation can also occur during diagnostic testing if any spark plug cables are removed and the engine is allowed to idle for a prolonged period of
time.
