Last time my car's engine warning light suddenly came on, it really freaked me out, so I quickly pulled over to check. First, I tried tightening the fuel cap—sometimes a loose fuel cap can trigger the alarm. If the light was still on, I would drive the car to a nearby repair shop to read the fault codes. In most cases, it's just a dirty sensor or a poor connection, and cleaning or reconnecting the plug will fix it. If the fault code shows serious issues like a knock sensor or a failed catalytic converter, then it needs proper repairs. Never drive long distances with the warning light on, as it can turn a minor issue into a major problem.
