Can the car still be driven when the small airplane light is on?

[CorbinDella]

The car cannot be driven when the small airplane light is on, as the small airplane light indicates a fault in the engine exhaust system. The causes of engine exhaust system failure include poor fuel quality, aging spark plugs, oxygen sensor failure, and coolant temperature sensor failure. It is recommended to use high-quality fuel for the engine. The function of the exhaust system is to collect, purify, and discharge exhaust gases. It consists of the exhaust manifold, exhaust pipe, catalytic converter, exhaust temperature sensor, car muffler, and exhaust tailpipe. The working principle of the exhaust system is that high-temperature car exhaust gases enter the purification device through the exhaust manifold. The purifying agent in the three-way catalytic converter enhances the activity of CO, HC, and NOx gases, promoting their oxidation. These three harmful gases are converted into harmless gases, thereby purifying the car exhaust.
