How can I tell a fuel tank cap is worn out?

A cracked or stiff seal, a cap that will not tighten down properly, or a fuel smell near the filler can all be signs. Inspect it with the engine off.

Can a bad fuel tank cap turn on the check engine light?

Yes, it can. A cap that does not seal may let fuel vapor escape and set an evaporative emissions code, and a shop can read the stored code to see what triggered it.

Why does the Motorad MGC218KA cap need to seal tightly?

A fuel tank cap closes the filler opening, so a tight seal keeps fuel and fuel vapor from escaping through it. A cap that does not seal leaves that opening partly open.
