Same problem with p0011 and p0021 codes....
I just finished up engine work, changed to CP pistons, new cosworth high flow, hi volume oil pump, and also new Brian Crower rods Stage 2..... 272.
i started the engine and it is doing fine runs great but i keep getting those two codes.....i have done 200 miles and engine is fine .. no oil ligth or anything wrong except for the codes......
I eliminated the small filter on the T that goes to the turbo and the passenger side AVCS... but them i keep getting the same codes.....
