Hello all,
On my 2018 STI I’ve been getting these codes and can’t figure out the fix. The ACVS on the left is only going to 2-3 while the right is up to 25-27. I’ve so far replaced the instale sprocket, intake Oil solenoid, changed and flushed the oil. I can’t figure it out. I’m using Motul 10W40 and this code followed me through a new build. I’m using a IAG stake 2+ block with new heads banjo bolts have been cleaned as well. I’m 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
