Code P0128, location of the coolant sensor needed

I got a code P0128, I replaced the thermostat and the problem exist. So I need to replace the Sensor. Part number 9LB26G004E. Also, I can clear the check engine light but I can't clear the code. The code scanner tool said the code is permanent. I hope once I replace the sensor the code will go away.

I was told that it is under the intake manifold. Do I need to take the manifold off in order to reach it in order replace it.
