Pressure Sensor giving bad values

I have the AMS5812 - 0001 - D differential pressure sensor and I am trying to operate it with an Arduino Mega 2560 currently. I used the sample code provided on the website but for some reason I am getting very weird values. The pressure will sit at around 0.03 PSI and does not change if I tap on one of the sensor tubes. The temperature is reading 98.75C every time I turn it on with no variance at all. I have two of these sensors and it is happening on both of them so I would assume the problem is on the software side but I can’t figure out how. Any help would be appreciated. This is the code I used:

#include <Wire.h>

// AMS5812 I2C address is 0x78(120)
#define Addr 0x78

void setup()
{
// Initialise I2C communication as MASTER
Wire.begin();
// Initialise serial communication, set baud rate = 9600
Serial.begin(9600);
delay(300);
}

void loop()
{
unsigned int data[4];

// Request 4 bytes of data
Wire.requestFrom(Addr, 4);

// Read 4 bytes of data
// pressure msb, pressure lsb, temp msb, temp lsb
if (Wire.available() == 4)
{
data[0] = Wire.read();
data[1] = Wire.read();
data[2] = Wire.read();
data[3] = Wire.read();
}

// Convert the data
float pressure = ((data[0] & 0xFF) * 256 + (data[1] & 0xFF));
float temp = ((data[2] & 0xFF) * 256 + (data[3] & 0xFF));

pressure = ((pressure - 3277.0) / ((26214.0) / 0.15));
float cTemp = ((temp - 3277.0) / ((26214.0) / 110.0)) - 25.0;
float fTemp = (cTemp * 1.8 ) + 32;

// Output data to serial monitor
// Serial.print("data1 : ");
// Serial.print((data[0] & 0xFF) * 256 + (data[1] & 0xFF));
// Serial.println((data[2] & 0xFF) * 256 + (data[3] & 0xFF));
// Serial.println(data[2]);
// Serial.println(data[3]);
Serial.print(“Pressure : “);
Serial.print(pressure);
Serial.println(” PSI”);
Serial.print(“Temperature in Celsius : “);
Serial.print(cTemp);
Serial.println(” C”);
Serial.print(“Temperature in Fahrenheit : “);
Serial.print(fTemp);
Serial.println(” F”);
delay(500);
}

To ensure there is nothing wrong with the sample code you could attempt using this alternative library:

does the sensor show up when you run i2c scan ?
