Common Check Engine Issues that Should Be Repaired ASAP

Few things are more stressful for drivers than seeing the check engine light illuminate on the dashboard. This warning can indicate a wide range of issues, some minor and others serious, and it’s not something to ignore. At Dream Motors LLC, we provide expert check engine light diagnostics and repair in the greater Ramsey, MN area. Here are four of the most frequent triggers for a check engine light.
Faulty Oxygen Sensor
One of the most common causes of a check engine light is a failing oxygen sensor. This component measures the amount of unburned oxygen in your car’s exhaust system and helps regulate fuel efficiency. If the sensor fails, your car’s engine may burn more fuel than necessary, leading to poor gas mileage and increased emissions. Replacing the oxygen sensor promptly is also crucial to avoid damaging the catalytic converter.
Malfunctioning Catalytic Converter
The catalytic converter plays a key role in reducing harmful emissions by converting carbon monoxide and other pollutants into less harmful gases. When it malfunctions, not only does it cause the check engine light to turn on, but it also affects performance and fuel-efficiency.
Failing Spark Plugs or Ignition Coils
Spark plugs and ignition coils are responsible for igniting the air-fuel mixture in the engine. If they fail, the engine may misfire, run roughly, or struggle to start. Misfires are a common reason the check engine light comes on and should be addressed immediately.
Mass Airflow Sensor Problems
The mass airflow sensor measures the amount of air entering the engine, helping to ensure that the right amount of fuel is delivered for proper combustion. When this sensor fails, it can cause poor performance, reduced efficiency, and increased emissions.
