I dont have any clue what would cause this but I am in need of some help.

Driving today my boost gauge just stopped..it went to complete vaccum and now just has a blinking red light and no readings.

I am still getting boost so the problem is with the gauge.

Anyone have this happen before? ]

Wiring problem, need a new gauge? what!

 

what kind of guage is it?

 

What gauge is it? I would first check to make sure the boost line didn't come out of the gauge or the line didn't get disconnected from the boost source.

 

its a deft gauge

 

well he said its flashing red...and if its a DEFI and not "deft" i also have a defi, it has a wole module that goes to it and if u hit the set/warn button, theres a red light that flashes and the needle stays still as long as that red light is flashing. if thats not the issue then yes, obviously check vacuum lines lol

 

sorry typo of the "deft" and I know what you mean about the set/warn button and thats not what the problem is

 

boost sensor is bad. Typically if warning light is flashing and you havent messed with your control unit then 9/10 sensor is bad and needs a new one. Better off buying another gauge as the sensors are like 100+
