Id like to know for sure what it is, I tried everything I could while it was in the car, short of changing cam sensors

Thanks in advance CAR IS AN 04 STI USDM (SINGLE AVCS)

Hey Guys, Did anyone find an answer on this? i have the same issue on my 06 FXT. swapped out both solonoids for new and checked for filters on all banjo bolts with nothing in there. Passenger side ranges from 6-8 and driver side from 24-25

Good day

Now get time to troubleshoot an avcs issue I've been having. Solenoids advancing 6 degrees max. Duty is up to 94% tho. Cleaned the solenoids and same issue.
Some forums saying could be the neutral position switch faulty that disables the avcs. If it was disabled would there still be a 94% duty?

Was the AVCS disassembled? Usually these issues after disassembly are from improper reassembly. The circles NEED to be concentric. I have used a D battery before to make sure that they are aligned while assembling.

The aftermarket replaced solenoids were “lazy” according to the shop I ended up bringing my car to. They gave me some known good ones and swapped them in.
