Will the engine malfunction indicator light illuminate when the Chery E5 is powered on?

When the Chery E5 is powered on, the engine malfunction indicator light will illuminate during the vehicle's self-check upon starting. If the engine is functioning normally, the light will automatically turn off after the engine starts. Principle of the engine malfunction light: The engine malfunction signal is issued by the engine control unit (ECU), which governs all electronic components of the engine, including the electronic throttle, fuel injectors, alternator, fuel pump, etc., covering systems such as intake, exhaust, fuel, ignition, and timing. If the engine malfunction light illuminates, it indicates an abnormality in a specific system. To determine the exact issue, a diagnostic scanner must be used, as each vehicle brand has its own unique fault codes. Persistent engine malfunction light: If the engine malfunction light remains illuminated and does not turn off, it signifies that the engine parameters have deviated from normal. Excessive carbon buildup is a common cause of such parameter changes. If this issue is not addressed, the engine's combustion state cannot be adjusted back to normal, and the malfunction light will remain on without automatically disappearing.
When driving my Chery E5, I noticed that the engine fault light does stay on briefly after powering up. This is the vehicle's self-diagnostic process in action. During system startup—much like a phone displaying its logo when booting—it checks all critical components such as sensors and the ignition system. The light typically turns off automatically within three to five seconds. If the light remains on after the engine starts, there might be a genuine issue, possibly due to excessive carbon buildup or a faulty oxygen sensor. In such cases, using an OBD scanner to read the trouble codes is necessary for confirmation. I recommend paying attention to the light's status before each startup; developing this habit can help you detect potential issues early and avoid roadside emergencies. Regular vehicle maintenance is also crucial, as it reduces the likelihood of false fault light alerts and ensures safer driving.
