i have checked with this software and all sensors have the low values.

nop , palm rest is the chassis were you hand are on it when you're typing . and the sensor i think ( i think) its the one that connect near the left fan , on the left side of the ISL6236 there is a small socket , were a 2 pin flat cable connects

The sensor seems to be at the trackpad at that model.
If you buy one make sure you buy it with its cable as apple tells they are calibrated by the factory.
