Relative humidity and temp sensor data problems

General
1

I am using an HIH7000 digital RHT sensor form honeywell and am only receiving the values of 0 for RH and -40C for temp. I have used the sensor before and received expected data using the same circuit and code. The circuit runs off 3.3v, I have two 2.2k resistors on the I2C lines running to the voltage line. I am just using the example code from the HIH61XX library which worked splendidly the first time I hooked it up. What could be the problem now? Here is the code below:

SYSTEM_MODE(SEMI_AUTOMATIC);
#include <HIH61XX.h>

//  Create an HIH61XX with I2C address 0x27, powered by pin 0
HIH61XX hih(0x27, D0);

    void setup()
{
    Serial.begin(9600);
    // Begin I2C communication
    Wire.begin();
}

void loop()
{
    //  start the sensor
    hih.start();

    //  request an update of the humidity and temperature
    hih.update();

    Serial.print("Humidity: ");
    Serial.print(hih.humidity(), 5);
    Serial.print(" RH (");
    Serial.print(hih.humidity_Raw());
    Serial.println(")");

    Serial.print("Temperature: ");
    Serial.print(hih.temperature(), 5);
    Serial.println(" C (");
    Serial.print(hih.temperature_Raw());
    Serial.println(")");
    delay(1000);
}

Thank you!

Have you checked the pull-up resistors on the i2c lines?

I have 2.2k resistors on the I2C lines as indicated by the data sheet. The circuit is running off 3.3V and I checked to make sure that the whole circuit was receiving voltage.
