How to Troubleshoot When the Car Engine Warning Light Comes On?

[HeidiRose]

Here are the troubleshooting methods when the engine warning light comes on: 1. If the water temperature is too high or the oil pressure warning light is on, and you can clearly feel that the vehicle has a malfunction, you should immediately pull over and call the repair station for assistance to avoid affecting the engine's performance; 2. First, the warning light comes on to inform the owner that there is currently a fault in the engine system, and it should be inspected and repaired promptly. Secondly, this fault information will be stored and provided to the mechanic as a reference during repairs to resolve the issue more quickly; 3. To ensure the engine can continue running even when a fault occurs, if the detected fault has little impact on the engine's operation, the computer will simply ignore it, but in reality, the engine is not in an optimal working condition at this time; 4. If a more serious fault is detected, the computer will activate an emergency program, allowing the engine to operate under this program, but generally only ensuring that the engine can continue running without stalling.
