Default P000C and P0021 FIXED

Hello all,

On my 2018 STI Iíve been getting these codes and canít figure out the fix. The ACVS on the left is only going to 2-3 while the right is up to 25-27. Iíve so far replaced the instale sprocket, intake Oil solenoid, changed and flushed the oil. I canít figure it out. Iím using Motul 10W40 and this code followed me through a new build. Iím using a IAG stake 2+ block with new heads banjo bolts have been cleaned as well. Iím thinking it could be the sensor as I have not changed it or something wrong with the harness as before I had an issue where the harness got damaged causing a throttle issue not sending the single.

How could I test to see that the voltage is getting to the Oil solenoid?

Problem was the harness connector
