Pressure sensor output only 1023

Help please!

I am a college student have very little knowledge of Arduino (just from the web) and no prior experience. I am currently trying to have the Arduino read the output from a pressure transducer (spec sheet attached). This is a code I compiled from other user's sketches. The pressure sensor has a range of 0-1 psi However the only value I'm getting is 1023. Nothing below that. I have an external power source of 12V in the Vin on the Arduino board. Everything is connected by a breadboard. Is it something in my code or wiring, or did I fry the sensor?

In order to make any use of the data sheet, you need to tell us the exact model number of you sensor.

Which sensor do yo have.
The GP001-5 (current output, 2-wire) or the GO001-D (voltage output, 3-wire).

A sensor with a 4-20mA current output needs additional circuitry to convert current to voltage, before the Arduino can measure that.
