Check engine light on 06 accord with codes P0139, 0113, and 0102 what are they?

So the check engine on my ole ladys 06 accord 2.4L v-tec came on a few days ago and we got codes ran by a local parts store. This is what it showed

P0139 02 sensor low voltage 2nd sensor
P0113 IAT
P0102 02 sensor

my question is im assuming low voltage 02 sensor is a faulty sensor.
Whats a IAT? is the P0113 code the 1st 02 sensor and what exactly do these codes mean? Its not running rough or anything but wanna get it fixed.
thanks guys

Refer to this thread for P0113:

P0102 is for the Mass Air Flow sensor; so, if the car is an SULEV, it has a MAF/IAT sensor and it probably related to the same thing. Check the connector and try cleaning the MAF sensor.

P0139 is the rear secondary oxygen sensor.

thanks for the help man. Ill get some MAF cleaner today and see what happens. The car is SULEV. And the P0139 code just means I need a new secondary 02 sensor or will cleaning this IAT/MAF solve that reading as well?
