Q: My check engine light is on and the autozone said it's the fuel rail pressure sensor and its high. I am supposed to drive to Texas

Hi Kelly. A check engine light is typically triggered when a senor detects a mechanical or electrical failure within an engine or transmission component. It usually will be accompanied by symptoms. In the case of a fuel rail issue, the first problem will typically be shaking or engines vibrating, lack of acceleration or stalling problems. Whether or not you’re safe to drive inter-state is very difficult for us to give you a direct answer or not. I would recommend resolving this problem before your trip, by having a professional mechanic come to your location to complete a check engine light inspection.
