Does a Malfunctioning Catalytic Converter Affect the Car?

[HazelLynn]

A malfunctioning catalytic converter can affect various aspects of the car, including annual inspections, fuel consumption, power, and exhaust emissions. Below are the specific impacts: Excessive exhaust emissions: If the catalytic converter is clogged or fails, harmful gases such as CO and NOx are directly emitted, resulting in non-compliant exhaust emissions. Increased fuel consumption: A clogged catalytic converter disrupts the normal operation of the oxygen sensor, affecting the accuracy of the signal received by the engine. This leads to imprecise control of fuel injection, air intake, and ignition, naturally increasing fuel consumption. Poor exhaust flow and reduced power: This is more noticeable in turbocharged models. When high-pressure exhaust is required, a clogged catalytic converter restricts exhaust flow, affecting air intake and reducing engine power, resulting in sluggish acceleration.
