I wish that more detailed pictures were available outside of a Toyota Parts shop, there’s three coolant temp sensors as well as two thermo fan sensors, trying to find the faulty coolant sensor without a clue as to were the other two are hiding is a pain in the bum.

Unable to find/locate vvt sensor in my 1998 Toyota Vienta.
Haynes manual also doesn’t mention it

Vvt solenoids, or oil control valves. If you take the engine cover off, you will see them on the valve covers each side. Two wire connectors. They sink down into the valve cover and look kind of diagonal.
