2 Answers
The solution for when the engine malfunction indicator light comes on is: 1. After turning off the engine, turn the ignition switch to the ON position; 2. Open the hood and the fuse box cover, locate the EFI 30A fuse according to the diagram on the fuse box cover, remove it, and reinstall it after a few seconds; 3. Turn off the ignition switch, then turn it back to the ON position to start the car, and the malfunction light will be eliminated. Reasons for the engine malfunction light coming on: 1. Failure to perform regular maintenance, leading to increased operational burden on the engine; 2. Changes in the quality of lubricating oil during use, causing the oil to deteriorate; 3. Faults in the engine's spark plugs, ignition coils, fuel pump, or fuel line blockages.
When the engine malfunction indicator light comes on, as someone who frequently drives long distances, my first reaction is not to panic. I should first slowly pull over to the side of the road, find a safe place to turn off the engine, and then check basic things: like whether the engine oil is sufficient and if the coolant level is normal. If everything seems okay, it might be a sensor issue, such as a faulty oxygen sensor or mass airflow sensor. It's best not to continue driving, as a small problem could turn into a major failure, potentially causing the engine to burn out. I recommend directly contacting a trusted repair shop and letting them use professional scanning tools to read the codes for diagnosis. Regular maintenance, such as changing the oil and filters, can help avoid such troubles. In short, when the light comes on, don't delay—timely repairs can save you more money in the long run.
