Last time I encountered the engine light coming on, I remember it was due to a faulty oxygen sensor, causing the air-fuel mixture to be too rich and fuel consumption to skyrocket. Common causes for such situations also include aging spark plugs, a clogged catalytic converter, or a fuel system leak. Back then, I first checked if the fuel cap was tightened properly, then went to the repair shop to use an OBD-II scanner to read the codes, which revealed the sensor malfunction. It cost me a few hundred bucks to fix. I suggest you don't ignore this light, as it can affect emissions and engine longevity. Regular maintenance like changing spark plugs and air filters can prevent many issues. Keeping these tips within 160 words is quite practical for daily driving.
