How to Solve the Engine Malfunction Indicator Light in Eado?
2 Answers
If the engine malfunction indicator light in your Eado is on, you can follow these steps to address the issue: First, check whether the engine is running normally and if there are any issues such as shaking or emitting black smoke. If these symptoms are present, avoid restarting the engine. Specifically, if the red light is on, do not restart the engine under any circumstances. If the engine can be started, turn it off and wait for 5-10 minutes. Then, without pressing the brake, press the start button once or turn the key halfway to the 'on' position without depressing the clutch. The car will perform a self-check after powering on. Wait for 5-10 seconds and observe whether the malfunction indicator light on the dashboard turns off. If the light remains on, visit a service center as soon as possible to diagnose the issue. The service center can use a portable diagnostic tool to read the fault code, identify the problem, and perform targeted repairs. The engine malfunction indicator light resembles a water tap icon and comes in two colors: yellow and red. A yellow light indicates a warning, while a red light means prohibition. When the yellow light is on, it means some system parameters may be outside the set range, and the car can still be driven, but certain functions may be limited. When the red light is on, the car must be stopped immediately, the engine turned off, and further driving prohibited until the fault is checked. Common causes for the engine malfunction indicator light to turn on include: sensor failure, oil quality issues, poor mixture combustion, turbocharging problems, intake issues, exhaust problems, or anti-theft system malfunctions.
Last time I helped my neighbor deal with the engine light on their Yidong, I found it's essential to start with the basics. First, check if the fuel cap isn't tightened or if the seal ring is aged—such minor issues can cause fuel vapor leaks and trigger the warning light. Next, inspect the spark plugs, especially in high-mileage vehicles, as excessive electrode gap can lead to poor ignition. The most commonly overlooked issue is the oxygen sensor; carbon buildup over time can affect exhaust monitoring, and I've seen many cars fixed simply by soaking it in oxalic acid. Of course, it could also be a faulty thermostat; if the engine temperature doesn't rise, the ECU will trigger an alert. If the light comes on during highway driving, it's likely the PCV valve is broken, allowing oil to enter the intake manifold. I recommend first using an OBD device to read the trouble codes before taking corresponding action.
