N75 and N249 Location

[NastyNogaro]

Booyakasha,

I am receiving my new N75 and N249 valves today along with a new MAF from ECS due to some short circuit codes that shitted out the old ones. Where are these valves located and has anyone ever replaced them before? Anything I should be aware of or look out for while replacing them?

Here are the codes that made me replace them:

17955 P1547 035
Wastegate Bypass Regulator Valve -N75
Short-circuit to ground

17697 P1289 035
Recirculating valve for turbocharger -N249
Short-circuit to ground

16486 P0102 035
Mass Air Flow (MAF) Sensor -G70-
Signal too low

respect,

nasty

The N75 is under the passenger side engine cover next to the Y-pipe, and the N249 is under the Drivers side cover next to the ypipe on the opposite side! the N75 has three vacuum lines connected to it, there are the shitty onetime use clamps on them so you will probably need new clamps.. i believe the same is true with the N249, although i have never replaced or removed it! hope that helps

Awesome, thanks man. Hopefully these new sensors fix the problem.

Also, does anyone know where the intake camshaft position sensor (g40) is?

There is a short circuit to this as well.

I took a look under those engine covers and can't seem to distinguish which valves are the n75 and n249. Anyone have a picture of what it looks like, preferably circled or highlighted from an engine pic?

I wish these valves can just be bypassed, sort of like the VSV's on a supra.. can they be? I know people run an MBC in place of the N75, but I'm only on K03's. Can the N249 be bypassed so I don't have to worry about this crap anymore?
