If something electrical wasn't plugged in, I'd expect the ECU to detect that and throw a pretty explicit fault code. I think what you have here is a lack of boost and something with the airflow not right. My guess is something physical (rather than electrical) isn't connected properly or got left loose, but I don't know that engine well enough to venture a guess as to what it might be.

Depends on the level of FOD, no?


fod-control-signs-risk-series.png



9779 - Boost Pressure
P0235 00 [175] - Regulation Range not Reached
MIL ON - Confirmed - Tested Since Memory Clear


6307 - MAP/MAF <-> Throttle Position Correlation
P0068 00 [175] - -

Sounds like you either left a pipe loose or unhooked or left a rag in the intake?

OP did you recheck your work as per RTFB and use good old common sense, you know JPPSG?

I cleaned the MAF sensor and the error hasn't come back in 1,000 miles, could that have been the cause?

Yes, I think it's possible for a MAF sensor to be off enough to cause a MAF/MAP correlation code. More often though, a MAF sensor that's reading incorrectly will cause fuel trim codes. Then again, when you cleaned it, you took stuff apart and put it back together and I wouldn't rule out the possibility that doing so could have fixed a leak.

It seems that the supercharger bypass valve is faulty (057-128-063G) and is causing the car to go rich. Could that cause the 9779 - Boost Pressure P0235 00 [175] - Regulation Range not Reached error?

Update for those that read this later...

The Supercharger bypass valve wasn't directly throwing codes, but I was getting Oxygen sensor codes and system too rich. Every once in a while I would get 9779 - Boost Pressure P0235 00 [175] - Regulation Range not Reached, but it was intermittent.
I changed the SC Bypass valve (Back of the SC, 7 bolts and changes in 2 minutes). Car is running A LOT better and there is much more power especially at low RPM.
