Hi guys got an odd issue. My cooling fan stoped coming on when it get up to temperature no codes and the test function on my obdeleven seems to show that the fan itself runs fine it over heats but the temp gage dosnt go over 90c i recently replaced it aswell as the outher temp sender and the ac presure switch  (the presure switch was falty but i didnt have a tool at the time so i replaced all the sensors)  any advice  should i put the known working temp sensors back in or could it posibly be anouther issue
