TSOP is a thermal sensor error within the Trackpad cable. The sensor is just at the end where it connects to the trackpad.
So you do need to replace the cable to get the system back to working properly.
As I explained your system is running in reduced clocking CPU Safe Mode! Which explains your trackpad pointer being jumpy now!
You may want to get a good thermal monitoring app like [https://www.tunabellysoftware.com/tgpro/|TG Pro] That will allow you to see whats happening! A common issue I see is people over do the thermal paste or use the wrong type.
