The professionals at Meta Mechanics have cutting-edge diagnostics technology to swiftly and accurately establish why your CEL is on and what to do if you are concerned about it.

Here Are Some Of The Most Common Reasons Why Your Check Engine Light Is On

Catalytic Converter Malfunction

In order to reduce harmful emissions, the catalytic converter breaks down carbon monoxide into carbon dioxide. If your car’s catalytic converter is malfunctioning, you might see a drop in performance and an increase in emissions. It’s possible that the failure is due to anything other than the converter, such a blown head gasket, in which case replacing the converter won’t fix the problem. In order to resolve this issue, expert help is required.

4. Faulty Oxygen O2 Sensor

The O2 sensor, short for “oxygen,” is used to determine how much oxygen was not used throughout the exhaust system. The information is sent to the vehicle’s central processing unit, which then adjusts the air and fuel ratio in the engine cylinders. If the oxygen sensor fails, it may damage excessive fuel consumption and even more severe wear on the engine and other parts of the vehicle.
