I have a 2013 Outback 3,6R that has been throwing code P0300. After replacing the plugs and ignition coils, the code has not gone away. Instead I now have a new code P0014. I came across a post here suggesting that the misfires could be caused by a failing OCV (VVT) solenoid.

I removed all 4 solenoids and cleaned them but the car still throws the codes. So I want to replace them but the Subaru parts fiche only shows 3 of the 4 part numbers on it and is confusing. Can someone help me identify the part numbers by location (Top Left/Intake, Top Right/Intake, Bottom Left/Exhaust, Bottom Right/Exhaust)? I don't think I have it correctly as the arrows in the diagram (see link) seem misleading.

VVT Solenoid 10921*A (Top Left/Intake) - 10921AA110
VVT Solenoid 10921*B (Top Right/Intake) - 10921AA190
VVT Solenoid 10921*C (Bottom Left/Exhaust) - 10921AA200
VVT Solenoid 10921*C (Bottom Right/Exhaust) - 10921AA200

Odds favor it's an exhaust Solenoid, they're more prone to 'stick'. Some owners give them a good cleaning, reinstall, and they're good to go. I simply replaced the one that was sticking in mine after the lockdown in 2020. - Not running the vehicle long enough to get her hot regularly, seems to make them more prone to stick or respond slow, causing the code/CEL to illuminate.

BTW PO0014 is for Bank #1, cylinders 1, 3, and 5....Passenger side, lower exhaust cam advance solenoid.

RockAuto has part# 10921AA110 as the exhaust solenoid for both left and right (Beck/Arnley manufacturer). This contradicts the image from Subaru which shows 10921*A (10921AA110) as left intake solenoid.

Your part numbers are correct for your car

The part numbers I gave you are correct for your car. the error was saying x2 for the 200 part vs 110 and for that I apologize for causing you an issue

Also the Subaru diagram is misleading and does not specify whether the part number is for the intake or exhaust solenoid as the location arrows are incomplete and hidden. For whoever reading this post in the future, please refer to the photograph to accurately figure this out.

I just took them out one at a time and matched 'em up also you MUST change your oil and filter when you do this job

Actually I did not change my oil and filter because I had done it <1000 miles prior and did not feel like throwing away good oil. The intake solenoids (top of the head) can be taken out on flat ground as they are high up and oil will not flow out. For the exhaust solenoids (bottom of the head), I parked on a uphill slope and drove the front wheels over a 2x10 board that was lying around. Put the parking brake on. Open the 10mm bolts and then use a soup container to collect the tiny amount of oil that flows out. It worked for me. The 2x10 board gives just enough clearance to work underneath without the need to jack up the car.

If you do find that your solenoids are gunked up (mine were not), then perhaps you should start with the oil change.

wow that's not good, service procedure states to use new oil and filter.

the inside of my engine has absolutely no varnish on it, it was amazing the crank, oil pickup connecting rods and timing chain are all original colors. I know this because i replaced my lower oil pan and looked in there.. ditto when you look down the oil add port... all nice shiney bright aluminum.

rare for them to get gummed up, more likely they leak or solenoids gets weak and they do not actuate properly resulting in poor idle
