GP2Y0D805Z0F Sensor permanently triggered

Hello people,
my GP2Y0D805Z0F Sharp Infrared Distance sensor https://www.pololu.com/product/1132
is permamently triggered. And it's hard to change the wiring or position so I'd like to be sure why that is the case. So my question: Does anyone know whether it has something to do with the wiring or the position.

Thanks in advance!

line #6 in your code has issue

The code is completely irrelevant in this scenario.
