I have Prius plus+ EU version, and i found this sensor, but.. i cant find any cable to connect, what kind of sensor is this? I drove +3 years and ~250.000km (now clock shows ~600.000km) without this sensor.
Its on the top of engine - right side, similar place where egr is Please look at the second pic edit: I think i found what its is, can it be coolant sensor connector? but my engine doesn't have coolant sensor there, its in another place. what do you think, right?
