Question Got P0a00 and P0400 codes..

I know the P0400 has been covered on this forum but didn't see anything on P0A00.

"Motor Electronics Coolant Temperature Sensor Circuit"

Cars seems to be running fine (00' ES). Temp gauge isn't erratic or anything like that. What type of symptoms do you think I should be looking for or possible sensors that need to be replaced?

Thanks for any help.
