You can read sensors with HWMonitor.
However trackpad failure can affects the results; need to replace for test.

Thank you for the reply. The screenshot of HWMonitor is attached. There are problems with palmrest and airport(?) sensors. However since I don't have spare trackpad, I can only try to pull out ?plug in the flex cablegram the trackpad again. It seems there are no more options. Is that so?

Is sensor attached on the trackpad or on the cable. Trackpad works without any problems.

Palm rest temp sensor is on the trackpad board.
Fan goes to full spin, if SMC cannot talk with that sensor.
You cannot test disconnecting trackpad cable.

More sensors are connected on the same bus.
If one fails, SMC gets confused and reports various erroneous values.
