Question about 1998 Cadillac DeVille
Car is in storage mode, displayed on the dash
Check for fuel and spark, if both are there then it could be the compression and or blocked cat converter in the exhaust system.

you can reset the system by turning key to on position for 5-10 mins and then try starting it but its probably a short or grounding prob try the engine to chassis ground

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.

I have a 1999 Cadillic Deville. The low Frefrigerant indicater come on after about 15 minutes of disconnecting the battery power. Each Time I reset the power the air conditioner comes back on for a while then goes out. I have taken it into the local auto repair place and they find no problem with the unit.
Could this be a intermittent connection to the computer. They have replaced both sencors and the problem persists. Where is the computer located on the car that handles this AC sensor message?
