What Causes the Engine Light on the Car Dashboard to Illuminate?

[MaryLee]

There are several reasons why the engine light on the car dashboard may illuminate: 1. The battery is dead, which not only triggers the battery indicator light but also the engine fault light; 2. The car has not been maintained as required; 3. When the engine oil is insufficient, the engine oil indicator light comes on, and the engine fault light also illuminates; 4. Lack of various fluids such as antifreeze, brake fluid, and power steering fluid; 5. False alarms from the electronic system. The engine fault light may appear in different ways: steady yellow light, flashing yellow light, steady red light, or flashing red light. If the red light is on, it indicates a severe fault, and it is recommended to go to a 4S shop for inspection immediately. If the yellow light is on, the fault may not affect driving, but it is still advisable to get it checked as soon as possible.
