What is the issue when the fault light of Chery E3 is on?
3 Answers
Chery E3 engine fault light may be on due to sensor failure, intake pressure sensor failure, or unstable circuit in the engine fuel injection system. Sensor failure: The system reports a fault code, but it works normally, which may be caused by an operation beyond the control range of the computer. Solution: You can first clear the fault code and then check if it reappears. Unstable circuit in the engine fuel injection system: Loose or broken connections in the engine fuel injection system can also cause the fault light to come on. Solution: It is recommended to go to a 4S repair shop for inspection and repair.
As an owner of a Chery E3, I've encountered the check engine light coming on several times over the years. Initially, it was quite concerning, but I later learned that this usually indicates an issue with the emission system or the engine. Common causes include a faulty oxygen sensor, a clogged catalytic converter, or a loose fuel cap. Once, after the light came on, I discovered it was due to poor fuel quality, and switching gas stations resolved the issue. However, more often than not, it's necessary to visit a workshop to read the fault codes with a computer for an accurate diagnosis. For safety reasons, it's best not to continue driving when the light is on to avoid causing more serious problems, such as engine damage. During regular maintenance, paying extra attention to checking sensors and wiring can prevent many unexpected issues.
I have considerable driving experience, particularly with models like the Chery E3. When the warning light comes on, my first thought is that a component in the engine bay is signaling an error. Recalling a similar incident last time, it was a minor fault in the engine's fuel injection system that affected emissions. The inspection steps include visually checking for loose or burnt wiring, then connecting an OBD scanner to the port to read the codes. Common codes like P0171 indicate a lean fuel mixture, while P0420 points to catalytic converter issues. Don't hastily clear the codes, as this might mask serious underlying problems. If handled properly, the issue doesn't always require major repairs; sometimes a simple cleaning or replacing a small component will suffice.
