SOURCE: Error Codes

These may have been set by the battery change and are what GM calls phamtom codes, clear the codes with the following.
Try this and see if the codes go away.

1. Re-enter diagnostics via the climate control panel and after all the codes appear you will see .7.0

2. Simultaneously push and hold the OFF and HI (^) buttons on the climate control panel until you see E.0.0 and release both buttons.

3. Turn ignition key OFF, Wait 15 seconds and re-enter diagnostics and see if the codes reappear. If they do NOT reappear, You are good to go.
After you have done this try starting the engine and see what codes re-appear, also run and OBD 2 test of the system at the diagnostic connector, this will give P codes that we are better able to find definitions for, the E codes are unique to just a few GM cars.

SOURCE: 1992 cadillac Deville OBD code read out and what it means.

E13-Oxygen sensor voltage stays between 0.307 and 0.609 volts for 64 seconds. Engine was at normal operating temperature at a speed over 800 RPM.
E44-Right oxygen sensor was lean for more than 50 seconds when engine was warm and at 800 RPM or greater.
E52-PCM has lost primary battery power.
E58-Pass Key fuel enable was not correct.
F47-PCM has received bad data from IPC for 3 seconds while engine speed was 500 RPM or more for 3 seconds.
F48-EGR open command was given during off idle operation. EGR opening should cause the mixture to be slightly richer because of the low oxygen content of exhaust gas. Vehicle speed was over 35 MPH and engine was warm.
Good luck and hope this helps, keep me posted be glad to answer any questions you may have.
