Where is temperature sensor on iPhone 5?

Hello. I have new iPhone 5, which was manually damaged (don't ask me how). To make it work again I've replaced lightning connector, battery and now i can turn it on and charge it. But now i constantly see message of Temperature overheating (iPhone needs to cool down before you can use it) and i can not use iPhone (except for emergency calls). iPhone's screen is turning down every 5-8 seconds so i have to turn it back on by pressing Home or Power buttons.

When i connect it to iTunes iPhone begins to sync but never finish it because when screen is turning down the sync stops too and iPhone disappear from iTunes (like when i manually disconnect USB cable)

Probably there is a problem with temperature sensor and i have to replace it too but i can not find it. Please help.

Not sure if it helps but i've lost a metal shield which covers LCD's cables.

There are five of them. One is in the battery, the rest are in several locations

R108 is at almost top of the board, test point XW9

R110 is beside the main camera connector, test point XW11

R57 is beside the A6 chip, test point XW15

R90 is at the bottom back of the board, beside an RF PA, test point XW33

All test points are beneath the SIM slot, check if anything is stuck between them to short anything out

All sensors are 0201 components, they are extremely small, almost impossible to work on

Look for board layout print on the internet to locate the parts
