I used a multimeter to measure the resistance of both temperature sensors and values are just like the FSM states.At 176F I get 0.33 for the ECU sensor and 49 for the dash sensor,so both are indicating the same temperature.If one of them wold be broken they wouldn't match,and also keep in mind that when they broke they usually have infinite resistance or 0 resistance,so I'm 99% sure they are working like they should.
