HSC sensor giving wrong values

Hello ,

I am using a pressure sensor HSCDRRN400MD2A3.
I am trying to read data from it and time stamp it.
I have pull ups for I2C PINS (4.7K OHMS)
I am using promini 3.3 V to power it.
The pressure sensor reading shows 374.99 no matter what input pressure I give. The sensor worked and gave correct values.
The timer DS3231 which also uses I2C pins , gives the correct value of the time.

What is the problem?

Thank you
