If the car's spark plugs are worn, dirty, the high-voltage wires or connectors are damaged, the Check Engine light will light up. This error affects the combustion of fuel and gas mixture because the spark plug is weak or does not light at the right time.

The Oxygen Sensor is a tool that measures the amount of oxygen in the exhaust gas and transmits information to the ECM. As a result, the ECM can re-adjust the gas, fuel and ignition timing for optimal performance. If the oxygen sensor has a problem, it will lead to incorrect information transmission, inefficient combustion, and more fuel consumption.
So, damaged oxygen sensor may cause the vehicle to display an error of the Check Engine light.
Gasoline vapor control system has the role of bringing gasoline vapor through the filter to the combustion chamber and avoid escaping from the fuel tank to the environment. The Check Engine light shows an error when this system has a problem.
The thermostatic valve works to maintain the engine temperature from 80 to 95 degrees Celsius by regulating the cooling water circulation system. When the valve encounters a problem, it will affect the cooling effect, causing the car engine to heat up. If this is not resolved in time, the device may be locked.
