Having Problems with your stock boost gauge & dont want to replace it with a tacky after market one?
Well I came across this issue with my R34 GT-T 1998 Skyline 1 month after getting it shipped over from Japan.
The Boost Gauge started not working & then working intermittently…
Started really annoying me & I knew it was a sensor of some kind as the engine was running perfectly fine.
After some research I found the culprit.
Right next to the break master cylinder is a oval shaped black sensor that has a small vacum hose that feeds directly off the inlet manifold.
The hose & wiring to the sensor were fine so I disconnected the sensor & took it inside to my work bench.
Be careful when opening the sensor the clips can be broken really easily (be delicate)
I discovered that the solder on the 3 main joints was not transferring current well at all & sometimes didn’t at all.
I busted out my soldering station & used some fresh solder to re-flow (re-melt) the solder joints. Just for safety measures I also did this on all major sized solder joints.
After that I put it all back together & hooked it all back up.
its been 3 weeks now with out a single issue.
