Airspeed sensor not working

it was due to interchange of ports , the ports order from sending end of air speed sensor was 5v,SCL,SDA,G but on the other end also must be in same order (once check on other side of the wires arranged propely or not ) the 5v and scl pins on other side of my sensor has been interchanged . after solving that issues air speed sensor will be detected but it shows some negative values , for this u need to inverse the sensor tubes and test it again , now it works great .
