this is from the 03 elective supercharger surgery sticky:
You're not going to believe this frontierguy...
I found a video at YouTube that could be my truck. The supercharger clearly sounds exactly like mine does now. It's the guys second rebuilt supercharger and he had the third ready to bolt on when they discovered it was the Knock Sensor all along! Now, why does that sound familiar?
"The noise you are hearing [in the video] is NOT coming from any components related to the serpentine belt system, including but not limited to, drive or idler pulleys. The noise is clearly evident, and is coming from the body of the supercharger where the roots / veins, are located. This supercharger is a rebuilt one, it is the second rebuilt supercharger which has been installed on this vehicle, and the third supercharger has arrived and awaiting installation.... The problem was a bad knock sensor, which causes the SC to go into bypass mode, causing the recirculation of air in the intake. What you're hearing is turbulent air."

I have an OBDCOM USB diagnostic program on the way for the shop laptop, as Autozone no longer does free code reads after they were sued by The Pep Boys. I also understand that the code can be simply witnessed (on Maximas apparently) by manually operating the ECU "Diagnostic Test Mode Selector" and watching the "Check Engine" light -it should pulse in first a number of long flashes, and then short to indicate any code conditions(?) The whole process is explained at a Maxima thread.

Not using hi-test gas will also raise havoc with the SC.
If the knock sensor is defective it usually retards the
timing, thus putting the SC in failsafe mode. Hence the
noise.Classification:
ECO4-011
Reference:
NTB04-083
Date:
July 14, 2004
2001-2004 FRONTIER AND XTERRA;
SUPERCHARGER NOISE AT IDLE AND LACK OF POWER
APPLIED VEHICLES:
2001 - 2004 Frontier (D22) equipped with supercharger.
2002 - 2004 Xterra (WD22) equipped with supercharger.
IF YOU CONFIRM:
^ The supercharger makes a rattle/grinding type
noise at Idle, and
^ The engine has reduced power while driving.
ACTION:
a. Review the supercharger information in this
bulletin.
b. If your incident is not caused by "park knock" as
described in this bulletin:
^ Go to ASIST for further diagnostic information
NOTE :DO NOT REPLACE THE SUPERCHARGER FOR A SPARK KNOCK
INCIDENT.
SUPERCHARGER INFORMATION
Premium fuel is required
^ The Supercharged (VG33) V-6 engine used in the
2001-2004 D22 Frontier and the 2002-2004 WD22 Xterra
requires Premium Fuel.
^ If premium fuel is not used, the engine may
experience "park knock" during acceleration or under
heavy loads.
^ If spark knock is detected by the "knock sensor",
the ECM will put the supercharger into bypass (fail-safe)
mode.
^ The supercharger will make a rattle/grinding type
noise at idle when it is in "fail safe".
^ Also, the engine will have reduced power if
driven in "fail safe".
Supercharger Bypass Valve
^ The bypass valve limits boost pressure from the
supercharger when the system is in fail-safe.
^ In fail-safe, the internal bypass valve will
remain mostly closed (see Figure 1).
^ After the key is turned OFF the ECM will reset
and restore the boost solenoid function.
The bypass valve will function normally, and the
rattle/grinding type noise will be eliminated.

Dear sir, I am trying to understand the function of the bypass solenoid. If the ECM is putting the solenoid in bypass mode is it adding electricity to the solenoid or not? What is the normal operation of this solenoid? Why two vacuum sources? Also can you explain the bypass valve? When it is closed the supercharger is producing boost. Is that in the up position or down position, referring to the linkage at the bypass vacuum valve? I installed a boost gauge and I see at idle -0.6 or -0.7. When I accelerate it goes to +0.1. What does that tell you?

..
I have been having the same problem for about a
week. Some server tech may be on vacation.
BTW… This thread is about four years old but it shouldn’t
be a problem…
Good luck… I never had a SC.. Don S..
