![]() Check Engine Light This is the engine malfunction warning light. This light comes on when the On-Board Diagnostic (OBD) system indicates a problem with the way the engine is running. It could be something as simple as a loose gas cap or even a transmission problem. Use an OBD-II scanner to read the fault codes via the OBD-II port located under the dashboard on the driver's side. Don't ignore the check engine light, or your vehicle may go into limp mode. |
