my check engine light randomly came on today while driving.... help please?

 

AutoZone or Advanced Auto will flash it for free and tell you what's up. CELs come on for a variety of reasons.

 

ok yea it could be an error
just go to autozone and they can figure out the code for free
maybe u may need just to erase that code and so the light engine will go off
sometimes the engine light it appears just because the computer can take errors
or maybe u need to replace a part
could be a little sensor ,I'm over 70% that u need a sensor
