The reasons for a check engine light turning on can range from something minor like a loose gas cap to something more serious like a faulty catalytic converter. It could even be a sign of internal engine failure. Ignoring the problem can turn a potentially quick fix into a costly and time-consuming repair.

You'll normally be able to drive for a while after the engine light comes on (as long as it's not flashing), but try to avoid heavy acceleration and high engine speed. It's not advisable to drive more than another couple of miles without getting your car checked by a professional mechanic.

A flashing light indicates a more serious problem like an overheating engine or engine misfires, which can cause irreversible damage. If the check engine light is flashing, you should stop, turn off the car, and call for assistance.

Although it is usually possible to drive with your engine management light (EML) on, it is strongly advisable to have the problem investigated and fixed by a mechanic as soon as possible. If the EML light appears on your dashboard, then there is an issue that needs to be immediately addressed.
