A few days ago I installed a BOV on my car, and my brother was sitting in the car and nottice that the STOCK BOOST GAUGE wasn't getting any reading. We replaced the PRESSURE SENSOR, but it still wouldn't get any reading. Do you guys know what could have caused my boost gauge to stop working?

 

Bad gauge cluster grounds usually. You take the cluster out, and clean all the grounds and contacts. Usually fixes it.

 

Thanks J-Rat-
Same problem here.
I'll be going after it this weekend

 

Get an aftermarket one, the stock one is crap anyways.

 

The stock one let's you know if there is a problem related to the pressure sensor. It would be advantageous if you could keep it working.

I had the same problem. I removed the gauge cluster, cleaned the contact terminals and that fixed the problem.

There was a time when I used crappy vaccum lines and it kept on popping off. The stock gauge let me know that the line popped off.

 

Exactly..

 

Yesteday i installed an aftermarket hks boost gauge and it worked fine, but the stock one still got no reading, i guess i'll try cleaning the ground contacts.
