little help

Those codes tend to be more common in the cold months on cars with lower temp thermostats and lower fan settings. It's not necessarily a sign of a bad sensor. The PCM is looking for a minimum threshold to be reached, sometimes there is also a time window involved, and if the engine is slow to come up to temperature, you can sometimes get a code.

This may be a potential explanation if all systems seem to check out.
