You probably fixed the problem with the sensor. Just under half on the guage isn't a bad temp to have. If the code wasn't erased it won't go away until at least 50 starts. Lyou havne' mentioned if it was erased or not. If after erasing and it still appears then you'll have to replace the thermostat. If that doesn't do it there may be another problem like a poor ground or a battery going bad.
