While the check engine light can indicate minor issues, it might also be alerting you to serious problems. Ignoring this light can lead to more extensive (and expensive) repairs, making it important to visit the shop ASAP. At A-1 Automotive, our local mechanics provide expert check engine light diagnostics and repair in the greater Portland, OR area. Here are five common reasons your check engine light might turn on. Failing Oxygen Sensor Oxygen sensors measure how much oxygen is unburned in the exhaust and helps regulate the air-fuel mixture. A malfunctioning sensor can cause poor fuel-economy, increased emissions, and potential problems with your catalytic converter. Replacing it promptly is essential to avoid additional problems. Malfunctioning Catalytic Converter The catalytic converter reduces harmful emissions by converting harmful gasses into less harmful substances. As the miles add up, it can become clogged or damaged. A failing catalytic converter can lead to poor performance, so addressing this issue is critical. Failing Spark Plugs or Ignition Coils Spark plugs and ignition coils are key components of your engine’s combustion process. If they’re worn out or failing, your engine might misfire, lose power, or run inefficiently. It’s important to replace spark plugs as called for in your vehicle’s maintenance plan. Loose or Damaged Gas Cap A simple yet often overlooked issue is a loose, cracked, or missing gas cap. The gas cap is what seals the fuel system. If it’s not secured properly, it can allow fuel to evaporate before you get the chance to run on it, as well as trigger the check engine light. Mass Airflow Sensor Issues The mass airflow (MAF) sensor monitors the amount of air entering the engine to ensure proper fuel delivery. If it’s malfunctioning, it can lead to rough idling, poor acceleration, and reduced fuel-economy.
