Cadillac Repair: 90 Cadillac Deville error codes, coolant temp, memory reset

Question
Hello, I have a 1990 Cadillac Deville and I recieved 2 error codes which are e052 - PCM Memory Reset & also e065 - Cruise - SPS Failure. What exactly needs to be fixed on this car?  

Answer
E052 only means that you disconnected the battery sometime in the past.

E065 in a 1990 year vehicle means CRUISE-COOLANT TEMP TO HIGH.

E065 in a 1991 year vehicle means Cruise SERVO POSITION SENSOR failure.

Most likely a faulty servo.
