The check engine light is one of the most dreaded alerts for drivers. However, it can turn on for a variety of reasons, some of which are relatively minor. The important thing is that you promptly visit the shop for diagnostics so the issue can be identified and resolved before it escalates. At Hye-Tech Auto, we provide expert check engine light repair in the greater Covina, CA area. Here are five common check engine light triggers. Faulty Oxygen Sensor Oxygen sensors monitor the amount of unburned oxygen in the exhaust system. When this sensor goes bad, it can lead to reduced fuel-efficiency and even cause issues with the catalytic converter. Ignoring a faulty oxygen sensor can result in more costly repairs, so it’s important to address this issue as soon as possible. Malfunctioning Catalytic Converter The catalytic converter plays a critical role in reducing harmful emissions from your vehicle. If this component fails, not only will your car pollute more, but you may also experience decreased engine performance. A malfunctioning catalytic converter often leads to a flashing check engine light. Faulty Mass Airflow Sensor The mass airflow (MAF) sensor measures how much air is entering the engine and helps your car’s computer determine the correct fuel-to-air ratio. If the MAF sensor malfunctions, it can cause poor fuel-economy, rough idling, or even stalling. Replacing this sensor is usually straightforward, but ignoring the problem can lead to engine performance issues. Loose or Faulty Gas Cap One of the simplest reasons the check engine light turns on is a loose or damaged gas cap. When it doesn’t form a proper seal, it can cause fuel vapors to escape, triggering the check engine light. Fortunately, tightening the cap or replacing it is an easy fix. Worn Out Spark Plugs or Ignition Coils Your car’s spark plugs and ignition coils are responsible for igniting the air-fuel mixture in the engine. As they age, these components wear out and can cause misfires, which will trigger the check engine light. Replacing spark plugs or ignition coils is relatively affordable and can prevent more serious engine problems in the future.
