When the car display shows an engine malfunction, it is mostly due to a fault in the engine's electronic control system. The specific troubleshooting steps are as follows: 1. Check the engine self-diagnosis light; 2. Monitor whether the engine coolant temperature is too high; 3. Check if the engine is low on oil; 4. Observe whether the engine is running smoothly. If any of these conditions are present, it is necessary to visit a nearby auto repair shop for maintenance. An engine is a machine that converts other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, electric motors, etc. For example, an internal combustion engine typically converts chemical energy into mechanical energy. The term 'engine' can refer to both the power-generating device and the entire machine that includes the power unit.
A few days ago, my car also had this issue. When the engine fault light on the display lit up, my whole driving mood went down. Usually, this problem occurs in a few areas: first, a faulty sensor, such as the oxygen sensor failing to detect changes in exhaust composition, causing the engine computer to mistakenly assume a fault. Second, fuel system issues, like clogged fuel injectors or insufficient fuel pump pressure leading to poor combustion. Third, ignition system failure, such as worn spark plugs or aging ignition coils. When this light comes on, don’t rush to drive too fast—first check if the fuel cap is tightened, as a loose cap can also trigger the light. If the light is yellow, you can still drive slowly to a repair shop, but if it’s red, stop immediately and call for assistance. It’s best to visit a repair shop and use an OBD device to read the fault codes for precise problem identification. Regular maintenance, like changing the engine oil and air filter, can help reduce the failure rate.
