What is your question?
02 readiness state is incomplete . Installed new 02 sensors but still not ready. Multiple fault codes for the h02 sensors are present.
How long has your 2004 GMC Sierra 1500 had this problem?

You'll never reach readiness if you have trouble codes. Diagnostic testing needs to be performed to resolve the trouble codes first. Then a drive cycle will be needed to set the diagnostic monitors.
