I had the same reading. I got an evap temp of 143 also. Talked to Gilly who said that there was no way it could be that high. Changed the sensor and found that it was updated to the one mentioned. Works fine for now. Still holding onto my Friday appointment just in case but on Thu night I will cancel it.
