If your check engine light flashes on, it doesn’t automatically mean that your engine is on the cusp of disaster. Still, you should promptly visit the shop for diagnostics so the issue can be pinpointed and resolved before it escalates. At Lloyd’s Automotive & Transmission Specialists, we provide expert check engine light diagnostics and repair in the greater Olympia, WA area. Here are five common check engine light triggers.
Faulty Oxygen Sensor
One of the most common culprits behind an illuminated check engine light is a malfunctioning oxygen sensor. Oxygen sensors play a crucial role in regulating the air-fuel mixture in your engine. When they fail, it can lead to decreased fuel-efficiency and increased emissions.
Loose or Damaged Gas Cap
Believe it or not, something as simple as a loose or damaged gas cap can trigger the check engine light. The gas cap is a crucial part of your car's emissions system, ensuring that fuel vapors don’t escape into the atmosphere. If it's loose or damaged, it can disrupt this system, causing the check engine light to illuminate.
Spark Plug or Ignition Coil Issues
Your engine's spark plugs and ignition coils are responsible for igniting the air-fuel mixture in the cylinders. When these components fail, it can lead to misfires and a rough-running engine, triggering the check engine light.
Mass Airflow Sensor Problems
The mass airflow sensor (MAF) measures the amount of air entering the engine, helping the engine control unit (ECU) adjust the air-fuel mixture. When the MAF sensor malfunctions, it can lead to poor engine performance, reduced fuel efficiency, and an illuminated check engine light.
Catalytic Converter Issues
The catalytic converter is a critical component in your vehicle's exhaust system, responsible for reducing harmful emissions. Over time, it can become clogged or damaged, leading to decreased engine performance and increased emissions. If your check engine light is on due to catalytic converter problems, it's important to promptly address the issue.
