Why Is My Engine Light On?

The engine management light can indicate a wide range of issues — from something minor like a loose fuel cap to something more serious like a failing catalytic converter or oxygen sensor. The only way to know for certain is a diagnostic scan. We will read the fault codes, interpret what they mean, and explain clearly what action is needed.
