When the Engine Light turns on, it's recommended to have the vehicle's diagnostic trouble codes (DTCs) read and diagnosed by a professional automotive technician or using an appropriate scan tool. The scan tool can help identify the specific issue or sensor triggering the Engine Light. Once the root cause is identified and addressed, clearing the DTCs using the scan tool can turn off the Engine Light if the problem has been resolved.
It's important to note that resetting the Engine Light without resolving the underlying issue may not permanently turn off the light. The light serves as an indicator of potential problems, and it's essential to address the root cause to ensure proper engine performance and avoid more serious issues in the future.
