Is it normal for the engine light to be on when the car is not started?

It is normal for the engine warning light to be on when the car is not started, as this indicates a self-check and that the engine is not yet running. Before ignition, the vehicle enters a self-check state, and this light (the engine warning light) will illuminate. It should turn off after the car starts normally. If the engine warning light comes on while driving, you should not continue driving. Engine: Check if the engine is running normally, whether there are issues such as shaking, black smoke emission, or difficulty starting. Avoid restarting the engine, as there is a high probability of an engine problem. Service Station: If the engine is running normally and the car can be driven, visit a service station as soon as possible to identify the cause. Wiring Harness Connectors: If the engine is running normally, the owner can try gently reconnecting various wiring harness connectors, as a loose connection might be the issue. Alternatively, repeatedly turning the key to the ON position may help resolve the problem.
I've been driving for over a decade and often get asked this question. When the engine light is on without the car running, it's actually normal - it's the vehicle's self-check system during power-on, just like a boot-up self-test. All dashboard lights will briefly illuminate to check if bulbs are functioning, and should turn off automatically after startup. If the light remains on after starting, then there's likely an issue, possibly a sensor malfunction or circuit abnormality, such as a faulty oxygen sensor or aged wiring. Don't panic - first observe the car's startup condition; if the light goes off during normal driving, no action is needed. For safety, I recommend checking dashboard light status monthly - developing this habit can prevent major troubles. If genuinely concerned, you can try checking if fuses are blown yourself, but for complex issues, visiting a professional shop is more reliable, saving both money and peace of mind.
