Hi all, I’ve seen very few posts of people experiencing this issue, some people just never return with a solution and I’m at my wits end.

This code will throw the car into limp mode and won’t go away until I clear it in FORScan.

I have changed the MAP, cleaned it, cleaned the MAF, checked all hoses and lines for leaks, changed the boost solenoid.

Next thing might be changing the DV? I have a GFB DV which was pulled out and inspected, re-oiled, etc.

At idle, my MAP voltage is 0.56V (seems low?) and when KOEOff, it sits at 1.62V. Can anyone comment on these values or share their experience with this code? I’m desperate for help. Thanks. IMG_4128.jpeg
