- Oxygen sensor problems. Faulty oxygen sensors can lead to rich or lean fuel mixtures.
- Engine misfires. Engine misfires can occur when ignition coils, spark plugs, or fuel injectors fail.
- Catalytic converter problems. A failing catalytic converter can restrict exhaust flow and produce a bad odor.
- EVAP system problems. The EVAP system prevents fuel vapors from escaping into the atmosphere. Leaks or failures in the EVAP system can cause this light to come on.
- VSC system problems. VSC is a system that helps to control the vehicle's stability. Problems with the VSC system can cause the VSC off light to come on.
It's important to have your car inspected by a qualified mechanic as soon as the check engine light and VSC off light come on. These lights can indicate a serious problem with your car, and neglecting repairs can risk your safety and cause long-term damage to the engine.
