Kinda bummed out. one week after buying my 2015 launch edition this code came on. Brought it to the shop 3 times, no one knows what to do with it. Next week I'm getting the camshaft sensors swapped out.

Anyone have any experience with this code? I just got it tuned by a pro with my cobb AP v3 and the guy said the car runs great which is why he thinks its faulty/dirty sensors. 49k miles btw.

Nobody ever had this code thrown before?? Well if thats the case I'll def document everything for future reference. Should be bringing the car back down to a private subaru tuner/mechanic to get the camshaft sensors replaced. I really hope that is all it needs.

One of the causes of the slow response (If it is the AVCS sensor) is material ending up in your oil. For example bearing wear, rings, cylinder walls etc will break down and that will end up in the oil flow to the point where it causes sensors that deal with oil pressure to have issues remaining accurate. Now when that does go on it is not from normal wear, most engines that experience this problem will ultimately need to be cracked open and re built. An easy way to diagnose this issue is when changing the oil the code should clear as it now has fresh oil with out material built up in it.


Another simpler cause is sometimes the plugs wiggle loose on the engine harness causing that code to be thrown, along with the actual sensors being dirty with build up maybe you could take them out and see if there is any oil on them to be wiped off?


Regardless changing the oil is a god way to rule out the first / worst situation.

Thank you for taking the time to reply, dude! So I had the oil changed, car tuned, and they cleared the light. It came back. Now it comes and goes. Like today it went away, I did a pull (5th gear redline) and it came back. But it comes and goes every few days. I bought the car used with 47k miles on it. When I got the car pro tuned with my Cobb AP v3, the guys said the car runs great so I hope its nothing serious. I bought it from a very small used car dealership (SZ Motorcars) like 6 weeks ago. I really hope its nothing serious and its just the sensors because I have no warranty.

Some information in this thread suggests that the sensors may not be the cause

P000D - swap cam position sensors to diagnose? - NASIOC
Thanks man. I came across this thread too because I have been googling the hell out of this code. I will have the subaru tech replace the solenoids and sensors because one of the code the car temporarily threw, was the turbo solenoid.

Do you guys think stuff like this would be covered in the 60 day warranty that comes with the used cars this dealership sells?

what is a turbo solenoid? :)

No-one thinks these may be ACVS cam gears? Yes they can get gummed up, and changing the oil may affect operation.

But_ these are new cars which leads to what nj-kiter wrote:

No problem a sure fire way to rule it out is send a sample of the oil out to be tested, though it sounds like it could be a electrical problem where the plug may be coming loose faulting the code, or something of that nature.


Are you able to swap the cam position sensors too see if the code follows the banks?

Lol “turbo solenoid “ was the exact words of my mechanic but I will Not lie, I am a complete noob. I am bringing my car down to the shop that dyno tuned my car (not the mechanic I referred above) bc this guy seems like he eats, breathes, and sleeps subies.

I got my oil changed when I got my car tuned about 3-4 weeks ago. I checked my oil levels yesterday and there was NO oil in there. I filled it up. No leaks but damn I know stis burn oil but almost 4 quarts in 3-4 weeks? Cmon.

Praying I didn’t buy a beat up POS. I’ll
Keep you guys posted on the resolution. The shop wants to check out the sensors next.

4 quarts in 3-4 weeks is *not* normal. i'd check oil consumption again (usually check at every fillup).

turbo solenoid *shrug* could be referring to the wastegate solenoid.

4 quarts in 3-4 weeks usually means cracked ringlands imho. if its not leaking or in your coolant the oil has to go somewhere. I'd do a compression check and see what your numbers are.

Yeah, def not normal. We changed oil again because it was dirty AF and removed, cleaned, reinstalled the camshaft sensors. That was yesterday. I drove it for about 2.5 hours since and the CEL has NOT come back.

Weird thing is, this CEL comes and goes. I had the CEL all week, I dropped it off at my guys shop with the CEL still on. I get a call when he gets in saying that there's no CEL. But we shall see.

Also, and to be honest I didn't check prior to this, but a few days ago I noticed there was zero coolant. So I bought this antifreeze (pic added, idk why lol) and filled it up. This was the same day I checked the oil and realized it had no oil. Needless to say I will be staying on top of my maintenance.

Sucks because I just bought the car on April 23rd and I've been dealing with this CEL since April 27th.

If it comes back (being optimistic with the "if"), we'll do a compression test and check the ringlands like you suggested, VA.

Thanks for all the suggestions and comments. I will keep this thread updated just in case it helps someone else out in the future.

So the CEL came back on. I attached a pic from my AP v3 reading the code. Oil just changed and levels are perfect. No leaking, no white smoke from exhaust. Car runs great, no issues at all. So the subaru guy said its a ghost code and he wants to delete it so it can never flag a CEL again. What you guys think?

i wonder if it's a bad OCV.

deleting the code to never turn on again? uhhhhh i dunnnnoooooo about that.

I can understand deleting a code to something like air injectors when u completely remove the airpump and 2ndary air injection system - but i woudl assume that the AVCS is vital to the car's functionality, and that knowing if the avcs cam gears are off is a big deal to the cars engine/performance? like if an OCV fails, isn't that bad news?

anyways, i'm just a DIY'er, i by no means know the intricacies of the AVCS/OCV.

I'd probably look into why you had both no oil or coolant. Seems to be symptoms of a bigger problem. Our turbos are both oil and water cooled and the original P000D code could be a symptom of a dead turbo filling the oil with metal and blocking the OCV sensors. Getting a compression check would definitly be first priority as I don't belive its a ghost code. I think someone above mentioned some filters near that sensor that you can check to see if they're blocked.

Good luck. A buddy has the same issue/code on a stock 2015. SOA cannot figure it out. They have had the car for weeks, motor out and done all sorts of stuff, said it was fixed and then boom, a day later it comes back. This now going on 7 or 8 months...

Id get rid of the car and start over. I'd be willing to bet this car was sold or traded in due to this code coming on.

OK, I will talk to my guy about this.

Ah man this is what I am afraid of. I def can't get rid of the car at least for another 3 years. Still owe way too much...as soon as its close to being paid off, I'll look into trading it in but since its the launch edition I was hoping to keep it for a long time and get a 2nd newer one in 4 years (when I paid it off).

But thanks for the replies guys, as much as it sucked to hear that last one lol. This was suppose to be an enjoyable purchase as I always wanted an STI but never pulled the trigger on it. I only have the car for not even 2 months and this kinda sucked the fun out of it. But i'll remain positive and hopeful and worst comes to worst, I'll just have to live with it for a few years..that was painful to type loll

Take it to a shop that can tell you what is going on. You'll be happy you did.
