Simply put, if your fuel cap light is illuminated, it implies that the computer has discovered a leak in the system, usually caused by a faulty gas cap. If this light appears while you are driving, stop immediately and secure the cap again. Within a day or two, the light should stop flashing if you keep driving normally while it is on. Check the gas cap for damage and replace it if necessary if the light doesn’t go out.
The computer may be misled into believing the gas cap is leaking if there is actually another leak someplace else in the system. Have a qualified technician analyze the problem and ascertain the source if the gas cap appears to be in good condition.

Your gas cap light is one of those lights that just provides information. All you need to know when this light turns on is that the gas cap is missing.

How can I identify a faulty gas cap?
A gas cap that won’t tighten all the way or one that is loose will be the most noticeable sign of a bad gas cap. At first glance, this might not appear important, but the entire fuel system could be exposed to dust and dirt if there isn’t an air-tight seal.
What location does the gas cap sensor have?
The gasoline tank pressure sensor, which is a component of the fuel pump system, is installed either within or on top of the tank. It is a component of the evaporative emissions system, often known as “EVAP) and measures fuel system pressure to find evaporative leaks like a malfunctioning or loose gas cap. Leaks can cause fuel vapors to escape into the atmosphere even if the EVAP system is designed to keep them from doing so.
When the sensor detects a leak or if the sensor malfunctions, it communicates with the engine computer and illuminates the “engine-light indicator. A fault code can be scanned by a mechanic to identify a sensor or evaporative emissions system leak as the cause of the issue.
The fuel tank may not need to be removed in order to fix an evaporative leak, but it normally does in order to check or replace a malfunctioning sensor.
What issues may an unfastened gas cap bring about?

The gas cap fault may be caused by other problems. It might be preferable to have a licensed technician investigate the gas cap issue. Although unlikely, damage to the fuel filler neck itself is a possibility. Even a new gas cap can not seal properly if it has any abnormal wear or damage. Even if the check engine light is not on or an EVAP system leak fault is present, it is also conceivable that there is an EVAP system leak or fault. The gas cap allows fuel tank fumes to be vented forward to the engine, where they are burned off during regular engine operation, in conjunction with parts like the charcoal canister and EVAP purge valve and/or solenoid. One of those might be the root of the ongoing gas cap light issue.
