Understanding Your Check Engine Light: Expert Diagnostics at Newmans Automotive in Austin, TX

Newman’s Automotive • July 2, 2025

Every car owner has experienced that uneasy moment when the check engine light flickers on. One of the most misunderstood components of vehicle maintenance, the check engine light (or CEL) serves as a crucial indicator of your car’s health. At Newmans Automotive in Austin, TX, we've made it our mission to demystify this often frustrating experience by offering comprehensive check engine light diagnostics.

This Little Light: What It Means

When the check engine light activates, it’s your car's way of telling you that something isn't quite right. This could range from a loose gas cap to more serious engine problems. The light is part of your vehicle’s onboard diagnostics (OBD) system, which continuously monitors engine performance and emissions.

Common Causes for the Check Engine Light

If your check engine light is on, it doesn't necessarily mean a costly repair. Here are some common reasons:

  • Oxygen Sensor Failure: Essential for maintaining engine efficiency, an oxygen sensor malfunction can reduce your miles per gallon, affecting fuel economy.
  • Loose or Missing Gas Cap: Often overlooked, a gas cap that’s not secure can trigger the CEL.
  • Faulty Catalytic Converter: Vital for emissions control, this issue can arise from prolonged neglect of your vehicle's health.
  • Malfunctioning Mass Airflow Sensor: This component tells your car’s computer how much air is entering the engine—critical for balancing and delivering the correct fuel/air mix.
  • Spark Plug/Plug Wire Issues: Faulty spark plugs or wires can lead to decreased performance and poor emissions.
