You can do an internet search for the list by looking for Cadillac OBD 1 code list.

The P041 code on your year model Deville is distributor related...either the hall effect switch and/or the magnetic pickup coil is defective...my guess would be the pickup coil. If your car has high mileage, you might want to consider replacing the entire distributor with a rebuilt one. Good luck, i hope this helps,

Firstly, they are al P type codes, which refers to PCM.

P0139 - HO2S (Heated Oxygen Sensor) Slow Response Bank 1 Sensor 2. This is is the sensor in front of the catalytic converter.

P0603 - Internal Control Module Keep Alive Memory error. This error normally comes up when the battery is disconnected.

P1139 - HO2S (Heated Oxygen Sensor) Insufficent Switching Bank 1 Sensor 2. (see above)

P1599 - Engine Stall or Near Stall Detected.

I hope this helps.....I would attempt erasing the codes first and see if they come back, and then going from there.

tHIS INFO ONLY AVAILABLE AT A CADILLAC DEALER PARTS DEPARTMENT YOU NEED DRIVERS LICENSE, PROOF OF OWNERSHIP BESIDES KEY CODE YOU WILL ALSO NEED THE CHIP NUMBER

change the air fow senser.

PO135 is oxygen sensor Bank1 sensor1. PO404 is EGR.
personally, I'd pull EGR off, clean pintle good with throttle body cleaner or carb cleaner, re-install, erase codes & try it for a while & see if it code(s) come back.

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.
