Geheren_ When you say you performed this twice, did you take it off and clean it thoroughly? Some have simply shot carb. cleaner or something that would dissolve some or all of the dirt that impedes the movement of the round cylinder. That is the easy way and I have no argument with anyone in how they choose to do the work on their own car, but I don't like doing things over down the road so I choose to do the very best I can the 1st. time around. If you took it off, how dirty was it? Something is definitely wrong if you took it off and cleaned it and it lasted 1 day. The cylinder should move freely and there is a procedure in the factory manual that you should be able to use to test it before you ever reinstall it or put the coolant back in. Maybe it needs to be replaced, but as with anything, I like to make SURE it needs the part before I put it on, especially at the price of Toyota/Lexus parts. Let us know some more of the details.
No other sensor that I know of.
I greatly appreciate your feedback, as it turns out I left 2 sensors unplugged, lucky the car even ran. Engine light went right out, car runs fine. Thanks
