Have you checked to see if there are any shorts or opens in the wiring going to the cooling fans and engine coolant temperature sensor? Also a faulty cooling fan relay can be the culprit These can be causes for these two codes p0481=cooling fan 2 control circuit p0118=engine coolant temperature sensor high input
