Electronic throttle code/limp mode

[Milvetmac]

So after 6,000$ I fixed my issue with the 2-5 times a day reset of the computer. I was using the AEM gauge to clear the code so I could keep driving and through an immense amount of research I found multiple issues that cause this code; throttle body, coolant temp sensor, accelerator pedal, injectors, dirt throttle body, maf/map sensor... so I replaced the injectors, pedal, glow plugs, throttle body, temp sensor, oil/trans pan, maf/map, reluctor ring, crank sensor, new intake manifold gaskets, cleaned ALL peripheral and associated parts (againx3), and added the banks system and I’ve been going 5 months now without throwing one code! Ted it cost allot but after 110000 miles and the price tag I have my truck back, better than ever and finally performing how I always wanted it to and am at least gaining my trust back in the truck. The only thing to figure out now is why it’s running so hot with minimal loads. Basic camping set up loaded and I’m running way too hot driving to the cajon pass with ambient air temp being 102 degrees my oil temp shots up to 246, trans 207, and coolant 230... any ideas?
