Rock Automotive • May 14, 2025

The check engine light is one of those car warnings that everyone dreads seeing, but it's also one of the most important signals that your car uses to communicate with you. Here at Rock Automotive in Kent, WA, we understand the mixture of anxiety and confusion this little light can cause. That's why we've dedicated ourselves to educating our customers and community, ensuring you're well-informed and prepared to handle this common automotive issue.

Why Does the Check Engine Light Turn On?

The check engine light is part of your vehicle's onboard diagnostics system, designed to signal problems related to the powertrain, which includes the engine, transmission, and related components. At Rock Automotive, we use advanced diagnostic tools to decode these signals, offering you clarity and peace of mind.

Common Reasons for a Check Engine Light

Some of the most frequent causes for a check engine light include:

  • Loose or Faulty Gas Cap: A loose gas cap can cause fuel vapor to leak, triggering the light.
  • Oxygen Sensor Issues: These sensors monitor the exhaust for unburned oxygen. Malfunctioning sensors disrupt fuel consumption and emissions.
  • Malfunctioning Catalytic Converter: If the converter fails, it affects the car’s exhaust system and environmental compliance.
  • Faulty Spark Plugs or Wires: These ignite the air/fuel mixture and are crucial for optimal engine performance.

What to Do When Your Check Engine Light Comes On

While it's tempting to ignore it, a persistently illuminated check engine light should never be disregarded. At Rock Automotive in Kent, WA, we recommend a methodical approach:

  • Check the Gas Cap: Ensure the cap is tightened properly, as this is a common trigger that's simple to rectify.
  • Observe Vehicle Behavior: Note any unusual vehicle behavior like reduced power or poor acceleration. Document these symptoms to provide a comprehensive report to our technicians.
  • Schedule an Inspection: Don’t wait too long. Schedule an appointment with the trusted team at Rock Automotive to have the issue diagnosed and addressed promptly.
