Computer problem
1999 Toyota Sienna 6 cyl Front Wheel Drive Automatic 72000 miles

I had my computer read the code for the check engine light and it was p0125.

By researching this it seem to be a coolant temperature sensor where is that located under the hood because I would like to install.

update on question it`s hard to see the diagram/picture you said it was located on the right side of the engine which number in the daigram is it?
