My Thermo king SB200 throws a code 41 check engine temperature, I check engine temp and it's fine, it's always between 198f and 203f , I put a new coolant temp sensor in and it still does the same thing, it does not do all the time, does anybody know what I can check to fix it?

I put a new head gasket on 2 months ago, it does not build up pressure , heat up or boil out the overflow, and it does not loose any antifreeze anywhere, it stays full of antifreeze I been checking it weekly.

Maybe it's best to get a download on it to see what's happening? it needs diagnosing for sure.
