Engine light??

[teen ti]

Hey everybody, I just got a new light to come up on my dash. It's an engine light, not the check engine light but a light of the engine and I've got no clue what this means. Please inform me of what this means and what I need to do about it. Thanks!

I don't see anything that looks like an engine in the owner's manual.
Can you take a picture or describe where it is between?

is your coolant temp sensor worn?
