2011 Sti Cel P0019

HeyBrandxn · 01-16-2017, 07:37 PM

Hello! As the title states, I'm popping the P0019 code on my 2011 STI. When the code comes in, the car still acts like it doesn't have a code (no limp mode, idles like it should, etc). I looked around everywhere trying to find out what the problem was, and I tried a few things to fix it. I've replaced the exhaust camshaft sensor, swapped to a good crank sensor, I've flushed the oil, and I've changed the timing belt and components and still have no luck. If anyone has some insight on this, please let me know! Thanks!

Good thing to check the timing belt but you'll need to dig a little deeper in this area to find out why the crank and cam in question still aren't correlating well.

Could be in the AVCS solenoid or actuator, perhaps a clogged screen right down to something as severe as a seizing camshaft that's sheared the drive pin at the pulley.

Thanks for the input! I was actually thinking it could be the solenoid. Where exactly is it? Or could you hook me up with a part number? I know there are OCVs near the fuel rails with the blue clips but would that one be for the exhaust side to? Or would it be the other clip near the cam sensor? And is there a sure fire way of testing to see if it's bad? Thanks again!

Bump; I'm still having this issue. Car continues to run like it does without a cel. I've now changed both Intake and exhaust ocv's. Anyone have any input?

Bump, My 2011 WRX STI is having the same issue, replaced the camshaft censor, had timings checked and multiple hot oil flushes. Dealership wants to do manual cleaning of the oil lines but unsure if that would even fix it.. Of course that wouldn't be covered by warranty either.

Could be that you need to clean the avcs cam sprockets themselves. I could easily see them getting enough grit in there to seize up. Might be easier to order new sprockets. Have you removed the filter screens?

Could definitely be the sprocket on bank 2 - service manual says to check/repair the following as needed

Quote:

Check the following item and repair or replace if necessary.
• Oil pipe (clog)
• Oil flow control solenoid valve (clog or dirt of oil routing, setting of spring)
• Exhaust camshaft (dirt, damage of camshaft)
• Timing belt (matching of timing mark)

They also say after the repair, you need to reset things

Quote:

After servicing or replacing faulty parts, perform Clear Memory Mode <Ref. to EN(H4DOTC)(diag)-61, OPERATION, Clear Memory Mode.>, and Inspection Mode <Ref. to EN(H4DOTC)(diag)-49, PROCEDURE, Inspection Mode.>.

how much are they charging to clean things? MSRP on the cam sprocket is $216, so not a super spendy part... if you aren't throwing both the p0017 and p0019, you only need the one that's suspect.

I've had the camshaft sprocket replaced, and a solenoid (AVCS i think) and/or a VVT Solenoid. and multiple hot oil flushes.

Before it threw P0019 there was a P0024 but I believe that was since fixed..

Most of what I'm reading now is it just could still be clogged?

They quoted me roughly $3000 for manual cleaning, mostly being labour.
