How to Eliminate the Engine Malfunction Indicator Light?

[WyattFitz]

The method to eliminate the engine malfunction indicator light is: start and turn off the engine three times in a row, disconnect the negative terminal of the engine battery, wait for about 30 seconds, and then reconnect it. The reasons for the engine malfunction indicator light to turn on include: 1. Sensor issues: When the water temperature, crankshaft position, air flow, or oxygen sensors are damaged, have poor contact, or signal interruption, the ECU cannot accurately obtain engine data; 2. Fuel quality issues: The gasoline grade added does not meet the specified requirements, causing engine wear; 3. Maintenance issues: Not maintaining the engine on schedule and poor driving habits increase the burden on engine operation.
