The majority of check engine lights that come “out of the blue” are emissions related failures, usually a leaky (or unscrewed) fuel cap, bad O2 sensor (~$40) or similar. Learning how to Google this stuff for yourself will save any vehicle owner hundreds of dollars instantly vs. spiraling into anxiety over having to pay a mechanic for what is, in most cases, something incredibly simple.
Fortunately, the specific equipment of a basic OBD2 code reader capable of both helping you diagnose and resetting the code is very cheap these days.
Very cheap.

Yeah, I got a basic reader about 10 years ago, for what would be €20 in today’s money. It’s saved me hundreds.
Only problem is motorbikes don’t have standard ODB2 ports so I have no idea why the light is on on my little 125 :-/
