2006 Chevy Equinox Hidden code $7EA / $7E8 I/M wont come to ready

2006 Chevy Equinox / Pontiac torrent 4300 V6 195,000 miles.
Fails NJ State emissions test I/M Readiness test.
No engine light but OBII code reader produces two codes $7EA and $7E8.
Engine runs great !

3 monitors are incomplete:

EVAP system INC
Oxy sensor monitor INC
Oxy sensor heater INC
EGR sys INC

I've run through the GM system reset procedure several times but no joy.
(driving at 55mph for several minutes and so on....)

Any help is appreciated

Used to be real talent here.

I'm a little baffled. Those codes are appearing on your scanner but are not actual codes. They actually appear to be sub menu codes. If your system is in any way "not ready" the check engine light must come on.

Yes... I see mention of them in google searches but no actual faults specified.

I'd take the vehicle to one of the majors like Pep Boy, Advanced Auto, AutoZone, etc where they will read the codes for free for you. Then you'll know exactly what the issue is.
