Check Engine Light Diagnosis in Carmel, IN
Seeing your check engine light turn on can be stressful. But not every warning means major engine damage. At Carmel Auto Repair, we provide accurate diagnostics to identify the issue quickly and fix it the right way.
Driving too long with the check engine light on can lead to more expensive repairs.
  • What Does the Check Engine Light Mean?
    Your vehicle’s onboard computer monitors engine performance and emissions systems. When something is outside normal range, it triggers the warning light.
    Common causes include:
    • Loose or faulty gas cap
    • Oxygen sensor failure
    • Spark plug or ignition coil issues
    • Catalytic converter problems
    • Mass airflow sensor malfunction
    A professional scan tool is needed to read the diagnostic trouble codes.
  • Flashing vs. Solid Check Engine Light
    🔴 Flashing light – Serious issue. Stop driving and have the vehicle inspected immediately.
    🟡 Solid light – Schedule service soon, but it may not require immediate towing.
    If you're unsure, it’s always safer to have it checked.
