Default ECC codes

My ECC was flashing every time I started up my car and I pulled the codes and got

40-Driver Air Mix Motor circuit open or shorted, or not calibrated

152-Keep Alive Memory lost; sets with battery disconnected

How would I solve these 2 problems? Also is code 40 a severe problem?

Have you unhooked the battery recently? Or any corrosion on the battery? These two things seem to make the ECC go crazy sometimes.

Here'* a decent discussion of a similar problem to yours, with some diagnostic methods to try:

Blinking ECC, Air Mix Seems to Work
