Why the Check Engine Light Appears

The check engine light is part of your vehicle’s on-board diagnostics system, designed to monitor essential components and systems. When it activates, it could mean anything from a loose gas cap to issues with the fuel, exhaust, or ignition systems. Ignoring the light can lead to further complications, so timely inspection and repair are crucial for maintaining your vehicle’s health.

This scan provides error codes that help pinpoint specific issues within the engine, transmission, or emissions system. By accurately diagnosing the problem, we can offer targeted repairs that save you time and prevent unnecessary work.
