I accidentally pulled the wire from the harness and need to know what part this is? (Its the one where the two wires are going into the block below the intake manifold near the front of the block)

It almost looks like an oxygen sensor but I doubt it is cause I thought they're both located near the exhaust manifold or cat.

 

maybe a temp sending unit or engine coolant temp sensor

 

Check your gauges to see if one of them is not working.
