How to Solve the Engine Malfunction Light Issue?

If the engine malfunction light comes on, you can follow these steps to address the issue: First, check if the engine is running normally and whether there are issues such as shaking or emitting black smoke. If these symptoms are present, avoid restarting the engine. Specifically, do not restart the engine if the red light is on. If the engine can be started, turn it off and wait for 5-10 minutes. Without pressing the brake, press the start button once, or turn the key halfway to the 'on' position without depressing the clutch. The car will perform a self-check after powering on. Wait for 5-10 seconds to see if the malfunction light on the dashboard turns off. If the malfunction light remains on, visit a service station as soon as possible to identify the cause. The service station can use a portable diagnostic tool to read the fault code, obtain fault information, and perform targeted repairs. The engine malfunction light is an icon resembling a water tap. It comes in two colors: yellow and red. Yellow indicates a warning, while red means prohibition. When the yellow light is on, it means some system parameters in the car may have exceeded the set range, and the car can still be driven, but some functions may be limited. When the red light is on, the car must be stopped immediately, the engine turned off, and driving must be prohibited until the fault is checked. Common causes for the engine malfunction light to come on include: sensor failure, fuel quality issues, poor mixture combustion, turbocharging problems, intake issues, exhaust problems, and anti-theft system malfunctions.
I've been driving for twenty years, and when the engine warning light comes on, there's definitely something wrong. Don't panic right away—first, check if the gas cap is tightened properly. Sometimes a loose cap can cause the sensor to give a false alarm. Then, listen for any unusual noises or vibrations from the engine. If there aren't any, you can try driving to the nearest repair shop. If the light keeps flashing or comes on while you're on the highway, pull over immediately and check—safety first. Remember, this light could indicate issues like an oxygen sensor problem, ignition system failure, or low fuel pressure. It's a good idea to do regular maintenance and use high-quality engine oil to prevent issues. If you often drive long distances, consider buying an OBD scanner to read fault codes yourself, making it easier to catch small problems early. In short, don't delay—get a professional diagnosis as soon as possible to avoid turning a minor issue into a major repair.
Last time my engine warning light came on, my heart was pounding. As a novice car owner, I learned to first observe the vehicle's condition: Does it start normally? Is there black smoke from the exhaust pipe? If not, check if the fuel tank cap isn't properly closed, as this is a common issue. Then inspect the engine oil and coolant levels, as abnormalities here can trigger the light. Avoid driving on highways rashly; find a safe place to pull over. The light might be due to a dirty throttle body or aging spark plugs, so it's advisable to visit a 4S shop for a professional scan of the fault codes. For prevention, change the oil filter every six months and keep the fuel system clean. Safety-wise, accelerate gently while the light is on to prevent potential engine damage.
