Typically on or right next to the thermostat housing. The sensor for the engine computer will always have two wires going to it. Older cars with temperature gauges on the dash used a separate sensor for that.
Those will always have just one wire.
What problem are you trying to solve? Temperature sensors have an extremely low failure rate because they have just one component inside them.
