Throwing Code P0068

[Picto]

Hi, I'm having a few trouble at the moment trying to tune up a VZ Holden 5.7ltr with ETB. I seem to hit this code "P0068" only at high rpm normally during a power run and i can't seem to get around it. The code is a MAP/MAF throttle position correlation code. It has also pulled code P0106 at the same time but not always together! I know that the P0106 is a map rationality test code and think i have got around that but this dam P0068 i just can't seem to get around! Anyone have any advice for me!!
Also not sure if this is connected or not but my trac control had de activated as well and can't seem to get it to come back on.
Happy to post the tune if it will help.

Thanks Heaps

Hi Picto,

That's a hard one, getting MAP to balance between P0068 and P0106... I take it you already played with C3003 and C2911...

If you post your tune then maybe someone will see what to do.

Anyone who wants to offer any advice either pos or neg would be welcomed.

Cheers

Try raising C2911.

Do you have a Freeze Frame record when P0068 happens...?
