* Worsen the problem: Ignoring the issue could lead to more extensive (and expensive) repairs later.
* Cause further damage: Driving with a malfunctioning part could damage other components of the engine.
* Reduce fuel efficiency: A problem indicated by the light might cause your car to burn more fuel.
* Lead to a breakdown: In some cases, the problem could cause your car to stop running entirely.
* Fail an emissions test: In many areas, a malfunctioning emission system will fail an inspection.
However, it's not always an immediate emergency. Some issues triggering the light are minor and won't cause immediate damage. A loose gas cap, for example, is a common cause.
The best course of action is to:
1. Get the code read: A mechanic or auto parts store can use a code reader to determine the specific problem causing the light. This is the *only* way to know the severity.
2. Address the problem: Once you know the issue, get it fixed promptly.
In short, while you might be able to drive a short distance, it's advisable to get it checked as soon as possible to avoid potential problems and costs. Driving long distances or under stressful conditions (towing, heavy load) is especially ill-advised with the check engine light on.
