Greddy boost gauge problem


TrickTT

Recommended Posts

I have a Greddy 60mm electronic peak hold boost gauge and it has developed a problem. It worked fine last time i used the car, but today, the warning light is flashing and it reads low. When the engine is off, it is showing about 400mm/hg vac (instead of 0) and the with the engine on, the needle sits right on the lower stop. I know the pressure signal from the manifold is ok as the avcr uses the same take off and that works fine.

I suspect the pressure sensor, but has anyone else had a similar problem?
