coolant temp sensor wires that plug in 2 it.

What is your question?

a while back i was replacing the coolant temp sensor and i saw that the 2 wires that plug into it had some bear wire showing i accidently touched the 2 together and there was a spark and now the engine light has come on, is there a fuse or relay that goes to that? i've looked up the codes and i been getting e-15 e 21. and both have been replaced still engine light is still on.

What makes this problem better or worse?

nothing
