6 methods to identify if a catalytic converter is malfunctioning:

• Check the dashboard warning lights:

A malfunctioning catalytic converter can trigger the "Check Engine" light on the dashboard.

• Listen for unusual noises:

A damaged or clogged catalytic converter can cause rattling sounds or a hissing noise coming from the exhaust system.

• Check for reduced engine performance:

A malfunctioning catalytic converter can cause a reduction in engine power and acceleration.

• Smell the exhaust fumes:

A failing catalytic converter can produce a strong sulfur smell in the exhaust fumes.

• Perform a back-pressure test:

or damaged.
