Three-way catalytic converter
Three-way catalytic converter - general information
• Keep your engine properly tuned. Certain engine malfunctions, particularly involving the electrical, fuel or distributor ignition systems, may cause unusually high threeway catalytic converter temperatures. Do not continue to operate your vehicle if you detect engine misfire, noticeable loss of power or other unusual operating conditions, such as engine overheating or backfiring.
A properly tuned engine will help
avoid malfunctions that could damage the
three-way catalytic converter.
• Do not park your vehicle over combustible
materials, such as grass or leaves, which
can come into contact with the hot exhaust
system and cause such materials to ignite
under certain wind and weather conditions.
• Excessive starter cranking (in excess of
one minute), or an intermittently firing or
flooded engine can cause three-way catalytic
converter or exhaust system overheating.
• Remember that tampering or unauthorized
modifications to the engine, the Electronic
Control Module, or the vehicle may be illegal
and can cause three-way catalytic converter
or exhaust system overheating. This
includes: altering fuel injection settings or
components, altering emission system
components or location, or removing components,
and/the repeated use of leaded
fuel.
NOTE
Unleaded fuel is required for vehicles with
three-way catalytic converters.
