The check-engine light is triggered by the vehicle's onboard diagnostic system when it detects a fault in the engine, emissions, transmission, or related systems. A stored trouble code narrows the source, but accurate diagnosis requires experience and proper tooling.
A flashing check-engine light often indicates an active misfire that can damage the catalytic converter. Ignoring a steady light can allow minor issues to become major failures.
We scan stored fault codes, perform a diagnostic inspection, identify the root cause, and provide a written estimate. Code scanning alone does not always reveal the full cause.
