Coolant sensor located on the hybrid?

It is tucked into the thermostat housing on the back side of the engine. Look where the coolant lines connect to the housing, the sensor is between them. If you are replacing it, drain the coolant down, then remove the sensor, apply sealer to the replacement and tighten to 15 lb ft, it is tapered so be careful as the housings crack very easily.

awesome thanks so much, this helps a lot. i know right where it is now in the back. thank you!

You are welcome,
