Common Faults In Car Emission Control Systems

Common Faults in Car Emission Control Systems

Common Faults in Car Emission Control Systems:

Faulty Oxygen Sensor

An oxygen sensor measures the amount of oxygen in the exhaust gases. A faulty sensor can lead to poor fuel economy.

Clogged Catalytic Converter

A clogged catalytic converter can restrict exhaust flow, causing reduced engine performance and lower fuel efficiency.

Malfunctioning Egr Valve

The EGR valve recirculates exhaust gas for emission control. A malfunctioning EGR valve can result in increased emissions.

Vacuum Leaks

Vacuum leaks can disrupt the air-fuel mixture, leading to rough idling and increased emissions. They should be promptly addressed.
