i would not trust it. get it verified through a scan tool to see the actual temp. if you are wrong and you overheat it, then you may do internal engine damage.

I ran it with scanner, temperature never got above 213.
How can fix the gauge misreading?

need to do a sweep test to check the gauge unit. then the temp sender unit needs to be replaced.
