Boost Gauge "stuck"

[Phatboy]

Hi all, on the MFD in my non-vspec 34 GTR the boost gauge is kinda "stuck" around 0.00, and doesn't move no matter what I do.

Sometimes restarting the engine makes it go down to baseline (-0.60).

Any ideas? Thanks.

0 just happens to be normal air.. you havent disconnected the line have you/

Yep - disconnected line from the sensor, have a poke around in the engine bay near the box for it.

Either that or the other end has come loose

Or... perhaps the sensor is dead? (most likely the above though)

run MFD diagnostics (covered in the howto section) and check the sensor

its either disabled or the sensor is toast or its unplugged

Look for "bad electrical connection/dry cct board joint" or, your sender unit is dodgy. Try sender substitution to exclude. Very difficult for vacuum to be intermittent I would think.
