My check engine light came on.
it started coming on on my way to fill my car, it was running at a very low fuel level.
i thought filling my car would solve the problem and it did for only a couple of hours.
i need a list of things that could cause the light to come on.
Your Engine Computer detected a problem, set a diagnostic fault code, and since that problem could adversely affect emissions, it turned the light on to tell you. The first step is to have that code read. Many auto parts stores will do that for you for free. It's important to understand that fault codes never say to replace parts or that they're defective. They only indicate the circuit or system that has a problem, or they describe the unacceptable operating condition. Reading the code is just the first of a long list of steps in troubleshooting the cause of the problem.
