You can always check the connections on the boost sensor/sender unit (engine bay, about 2" diameter, covered with an orange rubber thing) to make sure that's not your issue. Here are the basic resistance values to tell if the sender is working properly:

0.0 Bar 5 - 13 Ohms
0.9 Bar 117 - 129 Ohms

Of course you would have to take it off the car and put air pressure to it to see if the values are in line. Somewhere I have a complete mapping of resistance values for each psi pressure change.

I still have mine fully functional, in addition to an aftermarket gauge. Believe it or not, they're usually pretty close to each other. Maybe I'm one of the few lucky ones!
