Thermo-king tri pack red check engine.

So i have a 2017 tripack evolution that keeps having the temps on the WT1 sensor jump to stupid levels and shut down the unit (read 438,872,631 as the highest recorded temp) but when i laser the head or restart it the actual temp is 130-160 and reads the same on the software when i hook it up depending on how hot it is outside.

I have taken it to 4 thermokings so far and replaced the following.

Fuel pump
Oil pump
Water pump
Coolant lines (as in they switch it from closed to open loop)
Arctic package
Alternator
Updated computer twice.
All fuses in the box
The wireing harness
WT1 sensor
Oil pan
Fans
Condenser
And they hooked another computer to it that didnt fix the problem and switched back to the old one.

I keep getting errors 10, 18, 93, 6 and 35. Thermoking in ####cago is now saying i need an entire new APU and im a bit flumixed as this seems wrong. There is no coolant in the oil or vise versa, head doesnt seam to be cracked or broken and i have zero clues as to where to begin as ive knocked out everything i cant think of other then the thermostat.

 

I mean i can try it, im running out of other ideas lol. Its weird too because my tripack was working great then had an oil change and now its not.

 

I mean its better then a carrier lol......carriers are the only ones ive ever had catch fire.

Ill give it a try, at this point im entirely flumixed so what can it hurt. Whats really really weird is once i plug in my service tool it works flawlessly within 5 mins of unplugging it "red check engine of doom"

 

Welp get er into thermo king. Turns out some moisture got into the box somehow and caused a relay to short and kill my fuse box. Also had a bad thermostat and a few other sensors were dead.

Seems to work fine now but we will see if it STAYS working
