Check all adjacent components, following the schematic.
Pay atention to its sensors (Q5810/30/60) and their traces.

PCIE_CLK100M_SSD_P/N is shorted when SSD inserted and without SSD the diode reading is .300

Q5810/30/60 is readings are normal. Still replacing them just in case.

Check continuity between R5370/1 and corresponding pins of LIO Finstack Temperature chip.
You can use TMP 102 datasheet and 820-3057 LIO schematic as guide.

No schematic of its LIO board; use mentioned one as guide!
The thermal sensor is the same.
You don't need to identify LIO connector pins.

It can be SMC issue.
But keep in mind, SMC doesn't supervise any sensor in SMC bypass; no matter is thermal, or I/V sensor.

Did you check mentioned lines for continuity?

yes i did. seemed ok to me.
I installed a NEW SMC. now i need to program but this machine just refused to boot via an external drive .

The device is much faster now. only thing left is to program the SMC so that max fan spin stops
