What is the little yellow light on my dashboard?
The little yellow light on your dashboard is typically an indicator light that alerts you to a potential issue with your vehicle.

- Loose or damaged gas cap: A loose or damaged gas cap can cause the light to turn on, as it can allow air to enter the fuel system and affect the engine's performance.
- Malfunctioning catalytic converter: The catalytic converter is responsible for reducing harmful emissions, and a problem with this component can cause the light to illuminate.
- Misfiring spark plugs: Worn or damaged spark plugs can cause the engine to misfire, which can trigger the yellow light.
- Issues with the engine control module: The engine control module is the computer that manages the engine's performance, and any problems with this component can cause the light to turn on.
