I noticed the yellow light on my dashboard while driving before and thought it was a major issue. After asking around, it turned out it could be something as simple as the fuel cap not being tightened properly or a minor fault with the exhaust sensor. That time, it happened right after refueling, and tightening the fuel cap fixed it. However, it's not always that straightforward. Other causes, like worn ignition coils or false alarms from the oxygen sensor, can make the computer think emissions are exceeding limits, triggering the yellow warning light. If not addressed promptly, it could lead to increased fuel consumption or even more serious mechanical damage. Now, I make it a habit to regularly check these small details on my car and pay more attention to the engine sounds while driving to avoid potential issues.
