Also looking at this thread it looks like my cooling system is OK

Can I just clear the error code and forget about it? Do you guys know how to DIY clear the error?
Thanks for all your input.
I just looked over thread again. Doesnt seem like sensor cuz your temp guage is so near normal and dont think tstat cause car prob wouldnt get to normal temp on guage if open tstat.Should be able to use just about any obd2 scan tool to erase. Try take car for a good drive before you think its good for sure. Keep it revved around 4000 rpm in first or second so it doesnt get much wind( disconnect fan) see that tstat is opening or if it gets too hot. Could use laser temp gun on rad. Just some more tests if you want. Sounds good to me but just watch the guage and erase is prob good
