Trouble Code (P0118)

[felixm]

I have a 1998 chevy Cavalier with a 2.2L, my check engin light came on and I pulled the code. The code is (P0118 Engine Coolant Temp.Circ High Input), I changed the coolant temperature sensor and cleared the code, but it just came right back. I was told that there might be two coolant temperature sensors, is this true, and if so where is the second one? Am I missing something, could this be the computer?
Please help.
