1 Answers
"The engine malfunction indicator light may illuminate due to various reasons such as poor fuel quality, oxygen sensor failure, thermostat failure, etc. It is recommended to first inspect the vehicle, listen for any abnormal engine noises, and check if there are any issues with the exhaust. If the situation is severe, it is advisable to visit a 4S store for inspection and repair as soon as possible. Solutions for the Accord engine malfunction indicator light illumination: Many drivers notice that the engine malfunction indicator light comes on after refueling, but the engine operates and sounds normal upon starting the car. This is usually caused by fuel quality issues. Generally, adding a fuel additive or refueling with fresh gasoline after the current fuel is used up can resolve the issue. In such cases, the vehicle can continue to be driven without safety concerns. If the engine malfunction indicator light illuminates while driving, it is usually due to a problem with the engine sensors. From a repair perspective, one critical component is the oxygen sensor. Typically, such issues arise from problems with the front oxygen sensor, which detects abnormal data on the air-fuel mixture ratio. A repair shop can diagnose and replace the sensor using a computer. When the thermostat malfunctions, the engine malfunction indicator light may also illuminate. If the water temperature gauge fails to reach the ideal temperature (usually 90 degrees) for an extended period while driving, the engine malfunction indicator light will come on. Generally, failure to replace the coolant within the specified mileage or a malfunctioning engine radiator leading to engine overheating can cause the thermostat to rust or even fail. Recommended solution: First, thoroughly inspect the vehicle, listen for any abnormal engine noises, and check if the exhaust appears excessively black or blue. If the situation is severe, do not continue driving recklessly. Contact a 4S store for towing and arrange for prompt repairs."
