Engine Light Diagnostics in Livermore, CA 94550

When your vehicle's check engine light illuminates, it's signaling that something requires attention. This warning light can indicate a range of issues, from minor to significant, affecting various components of your vehicle. Whether you drive a Domestic Vehicle, Asian Vehicle, or another brand, understanding the cause of this alert is crucial.

Common Reasons for a Check Engine Light

• Oxygen Sensor Failure: A malfunctioning oxygen sensor can lead to decreased fuel efficiency and increased emissions.
• Loose or Faulty Gas Cap: An improperly sealed gas cap can cause fuel vapors to leak, triggering the check engine light.
• Catalytic Converter Issues: Problems with the catalytic converter can affect your vehicle's performance and emissions.
• Mass Airflow Sensor Malfunction: This sensor measures the amount of air entering the engine; issues can impact fuel economy and emissions.
• Spark Plug or Ignition Coil Problems: Faulty spark plugs or ignition coils can cause engine misfires, affecting performance.

Understanding OBD-II Diagnostics

Modern vehicles are equipped with On-Board Diagnostics II (OBD-II) systems that monitor engine performance and emissions. When the system detects an issue, it stores a diagnostic trouble code (DTC) and activates the check engine light. At Advanced Auto Works, our Reliable technicians use advanced diagnostic tools to retrieve these codes and pinpoint the exact problem.
