4 Common Check Engine Light Issues that Should Be Promptly Addressed

The check engine light on your dashboard is more than just a mild warning—it’s your vehicle’s way of telling you something is wrong under the hood. While some issues might be minor, others can lead to serious damage or safety concerns if ignored. When the check engine light comes on, it’s important not to delay diagnostics and repairs. At Brake Masters, we provide expert check engine light diagnostics and repair in the greater Camarillo, CA area. Here are four common check engine light problems that should be fixed as soon as possible.
Faulty Oxygen Sensor
The oxygen sensor monitors the amount of unburned oxygen in your vehicle’s exhaust and helps regulate the fuel-to-air ratio. A malfunctioning oxygen sensor can cause the engine to run inefficiently, leading to poor fuel-economy. If ignored, it may also damage the catalytic converter, resulting in much more expensive repairs. Replacing a bad sensor promptly helps keep your engine running clean and smooth.
Malfunctioning Catalytic Converter
The catalytic converter helps reduce harmful exhaust emissions by converting carbon monoxide and other pollutants into less harmful gases. If it becomes clogged or fails, your car will run poorly, and emissions will spike. With a failing catalytic converter, you might notice a smell similar to rotten eggs.
Failing Ignition Coil or Spark Plugs
Spark plugs and ignition coils play a key role in starting your engine and keeping it running smoothly. When they fail, you may experience rough idling, poor acceleration, misfires, or trouble starting the vehicle. Replacing worn-out plugs or coils quickly is essential to prevent further issues.
Mass Airflow Sensor Problems
The mass airflow sensor measures how much air enters the engine so the computer can balance the fuel injection. A faulty sensor can lead to poor performance, stalling, or hesitation during acceleration. It can also reduce fuel-efficiency. Replacing a bad sensor promptly can restore your vehicle’s performance and fuel economy.
