The check engine light can make any driver feel anxious. While its appearance might seem like a mystery, this dashboard indicator is your car's way of telling you something needs attention. At Bay Brothers Automotive, we provide expert check engine light diagnostics and repair in the greater Tampa area. Here are five common reasons the check engine light comes on.

Faulty Oxygen Sensor

Oxygen sensors monitor the amount of oxygen in your vehicle’s exhaust system, helping to ensure the engine runs efficiently. A failing sensor can disrupt your car’s fuel-air mixture, leading to poor performance, reduced fuel-efficiency, and increased emissions. Ignoring this issue could also cause problems with your catalytic converter, turning a simple fix into a more expensive repair.

Malfunctioning Catalytic Converter

The catalytic converter reduces harmful emissions by converting pollutants into less harmful substances. If your converter is failing, you may notice decreased fuel-efficiency, sluggish performance, or even a rotten egg smell. 

Mass Airflow Sensor Issues

The mass airflow (MAF) sensor measures the air entering your engine and ensures the proper fuel mixture is maintained. A faulty MAF sensor can lead to stalling, rough idling, or trouble starting the vehicle. 

Worn Spark Plugs or Ignition Coils

Spark plugs and ignition coils work together to ignite the fuel-air mixture in your engine. Worn or damaged components can cause misfires, reduced power, and poor fuel-economy. Replacing spark plugs and coils is a routine maintenance task that can help prevent the check engine light from appearing.

Loose or Damaged Gas Cap

A loose, cracked, or missing gas cap is one of the easiest issues to address. The gas cap seals the fuel system. When the cap isn’t secure, fuel may evaporate before your engine gets the chance to run on it, and the check engine light might illuminate.
