That is what they call a "generic" code. Some OBD11 or OBD2, "same thing", scanners will give a $7E8 and $7EA. together and maybe a $7E9.
These are for a sub menu. Click on each one separately and you should or might get a regular "P0" code if your scanner
has the supported module. If not either get a better scanner or
go to a "big box" auto parts store and they will scan it for free and
should be able to give you more information.
Please comment or feedback if helpful.

The o2 is just reporting information,it did not mean that it was bad,there is either restriction,in the cat,or there is a contamination in the fuel,an additive might clear it up,maybe.

What do the codes 7EA and 7E8 on a 2013 chevy captiva?

These are not trouble codes, instead they direct you to components that need to be looked at. Basically, the control module menus and both codes represent something. The 7e8 represents the engine powertrain, while the 7e9 represents the transmission powertrain.
