Can You Still Drive When the Engine Malfunction Light Comes On?

When the engine malfunction light comes on, you should stop driving immediately to protect the engine. Continuing to drive may cause damage to the engine. With the advancement in automotive manufacturing technology, the engine itself generally does not experience major failures. There are many sensors and electronic devices around the engine, as well as some critical components. If any of these parts malfunction, it may cause the engine to stop working properly, triggering the engine malfunction light. More details are as follows: 1. Sensors around the engine: These include the camshaft position sensor, oxygen sensor, coolant temperature sensor, knock sensor, air flow sensor, intake air temperature sensor, etc. If any of these sensors fail, it may cause the engine to malfunction. During repairs, technicians usually connect a diagnostic computer to the OBD interface to read the vehicle's trouble codes. These codes help technicians quickly identify the faulty part and the cause of the issue. Therefore, reading trouble codes is an essential and mandatory step in vehicle maintenance. 2. If the engine malfunction light comes on: It is recommended to immediately visit the nearest repair shop to diagnose and fix the issue. The vehicle's dashboard also features many other malfunction and warning lights. When these lights illuminate, they indicate a problem in a specific part of the car, and it is important to have it checked promptly.
When the engine warning light comes on, I strongly advise you not to continue driving. This light indicates there's an issue with the engine system – it could be a minor fault like a sensor false alarm, but it might also be something serious like fuel injection or ignition system problems. If you insist on driving, a small issue could escalate into major repairs, such as internal engine damage, which would be costly and dangerous to fix. With over a decade of driving experience, I've seen many cases where friends kept driving on highways despite the warning light, only to break down midway, doubling their towing and repair costs. Safety comes first – it's best to find a safe spot to pull over and inspect, or drive slowly to the nearest repair shop. Remember, if the light flashes, it's an emergency signal requiring immediate stopping. Regular maintenance focusing on sensors and emission systems can reduce such risks. In short, don't gamble with safety or your wallet – timely action is the wisest choice.
From a cost-saving perspective, it's best not to continue driving when the engine warning light comes on. The light might indicate a minor issue, such as an oxygen sensor malfunction causing increased fuel consumption, but ignoring it could escalate the problem and lead to skyrocketing repair costs. For example, continuing to drive might damage the catalytic converter, which could cost thousands to replace. My relative kept driving daily after the light came on, only to end up with a major engine overhaul, costing several thousand more. It's advisable to visit a repair shop to read the fault codes when the light appears—many places offer this service for free, allowing for quick problem identification. Addressing minor issues early saves money; if it's serious, early intervention prevents greater losses. Don't push your luck to save time or avoid hassle—it often costs more in the long run. Regular vehicle checks, such as inspecting the fuel system and ignition components, can also prevent the light from coming on. Financially, stopping for repairs is far more economical than risking further damage by continuing to drive.
