Have you tried looking for a used oem sensor at the junk yard? I'm not sure what they go for but you'll probably save some serious coin.

Years ago my old boss who's an electrical engineer mentioned having difficulty with after market sensors. He replace a coolant temp switch, or the one that turned on the fans, 3 times before realizing the new sensors were out of spec. He had bought them all at different auto parts stores. Knowing that was the problem he put in an oem and it fixed the issue.
