Question about 1995 Cadillac DeVille
Here is what your codes mean
T033 ........................................ RR Wheel Speed Sensor Continuity Fault
A011 .......................................... High Side Temperature Sensor Circuit
The TO33 is for your ABS and could be as simple as the plug being disconnected, I have had this happen to me when doing a brake job.
The AO11 is the high side AC temp control, which should mean that your AC system is getting overheated and can be as simple as wasing the condensor coil on your car. Just take it to a self car wash, open the hood and power wash all the coils and radiator.
If these don't fix the problems, you probably have bad sensors and will have to have them replaced.
