Cam Gear Troubleshooting on the FA20 -- P0016-9/P000A-D Codes

If you are getting the dreaded P0016/P0017/P0018/P0019 or P000A/P000B/P000C/P000D then you'll want to watch this video through. It is common on the Subaru/Toyota BRZ/FR-S/GT86, as well as many other cars such as the Crosstrek and WRX that use the same style phasers and solenoids.
The TSB is here: static.nhtsa.g... for the proper troubleshooting steps.

Спасибо за видео. Очень подробно. У моей сестры проблема с мотором fb20 уже на 35000 км. Замена местами соленоидов не привела к смене проблемы. Так же, я посчитал, что пробег слишком мал, что бы механизм изменения фаз уже стал неисправен. Но есть проблема с редкими короткими поездками. В моторе много черных отложений. Я посчитал что они засорили фильтры и сегодня мне придется снять мотор, для замены фильтров

We discovered a way to clear the learned values on Friday using a scan tool. This is great news for Subaru enthusiast and techs. We haven’t figured out the brz platform but have successfully reset a 2015, 2016 and 2019.

so would you be so kind and share with us how to clear learn values with scan tool, step by step thanks a ton

@@Samlol23_drrich about as helpful as the video............no response to questions. But if you buy their tune they would probably be more than happy to help. Pointless video. I am finally going to tackle this issue in the coming weeks. If I get it figured out I will report back.

[@Jewishcatfish]

2020 wrx here with the p0016 code... Crank Position-Intake Cam 1 (RH) Position Correlation. Changed out the Passenger side intake cam sensor before watching this video, and yeah CEL came right back seems to come back on at the same frequency/situation/mileage at deceleration. Will try swapping the intake camshaft solenoids from left to right next see if the code changes. Keeping my fingers crossed. I flex fueled my car, and only have 20k miles. Don't see the dealership over a hours drive away offering warranty work for this and i'm scared to ask... Ty for making this video!

[@sbrasileiro]

hey just got the p0016 on my 17 wrx what did you do to fix it?

[@Jewishcatfish]

@@sbrasileiro my car is a 2020 and I had it tuned. I tried to avoid the dealership, but it ended up at Subaru anyways. Dealership worked with me some with labor, but they replaced the camshaft phaser and engine ECU because the code was burned into the ECU and couldn't be cleared. Not cheap in my case. I feel your pain.

[@aniquosama]

@@Jewishcatfish i also have a 2020 wrx only has 15k miles and just got the p0018, how much did it cost you? And were you covered with warranty? Did you put it back to stock before going to the dealer? Sorry for the many questions

[@Jewishcatfish]

@@aniquosama I had to pay for a new ECU the manager had warranty cover the rest. It was over a grand if I remember correctly. I don't think there was a way for me to hide my modifications I was open and honest with the dealership and they worked with me. These cam phazer ECU burn in issues are dumb. Since 2013 this problem has been a issue i believe.. good luck

[@ThePathofEddie]

This same exact code just came on for me bro, i took it to the dealership and they told me they couldn’t diagnose it properly cos i have a big sf cobb intake, advised me to go back to stock so they can properly diagnose, were you able to get yours fixed? My car runs and idles fine, although I notice that there’s a difference in the acceleration, sort of feels slow, what do you recommend I should do

[@denniskeyser2212]

I know this is a little old, but I had this exact issue with a FA20DIT engine, bought from salvage yard, had P0016, after a lot of head scratching I ran the engine for about 100 miles on a clean oil change, then ran Subarus engine oil flush through it, one more oils change and the issue was completely fixed. I am able to watch the cam positions on my access port and I can see that the right intake stays right with the left intake now. I think the salvage yard engines sit around too long and the oils break/coat the journals, the flush turned my new oil completely black. I am going to do one more flush at 1,000 miles just to make sure.m

[@drdlugi]

There's no way around replacing ECU whenever you ingerate into timing chain?

[@AbrahamLingo]

Where can I find a video or resource on replacing the Oil Control Valve Filters?

[@CHAD10ize]

Did you find the video or any knowledge of where the filters are located?

[@Tniz86]

Is there a data log to show if its the cam gear thats the issue? If not is there another way to nail it down as the problem?

[@K03sport]

...of the two pieces, which one is more likely to fail? and which one is easier to replace? Personally, the sensor/phaser is easier to replace for simple troubleshooting....

[@rbailey225]

I'm flying solo on this. Paying labor is not an option. I have a decent grasp on mechanical skills and have plenty of experience. I have changed out phasers on a couple of bmw e39 V8 engines. Getting a code for P000A intake bank 1 slow to respond. Oil solenoid checks out good. Is there a way to determine if it's the sprocket or the OCV filter? Engine has 52000 miles. Never been rebuilt. It did sit for a year due to an accident. Can air be blown into the cam phaser check ball area to dislodge any possible sludge in the filter? Or, do I have to remove the phaser and blow air directly into the oil hole on the cam? I did an engine flush with no change in result. It would be a shame to replace the sprocket only to find out I have a clogged OCV filter. Are all of those data PIDs available in a high level scanner? This was an engine swap and I am using a 2014 ECU on a 2016 engine. Should I swap in the 2016 ECU? They both have a stock tune. This is an FRS.

[@johnborja9391]

Scion frs same issue code p0016 and p0018. Changed out clutch and flywheel car has been sitting for over 2 months. When trying to start car it takes 2-3 seconds or more to crank and start. Then idle goes up and down. I would have to accelerate pedal for car to not die out. Even if driving once let go pedal will auto die. Someone mention the flex plate behind the flywheel may be damaged or not installed correctly. My last option is to pull out trans to check or to replace ecu. Any idea what issue is?

[@skyty0]

Did you ever figure out how to fix this? I have the exact same issue, down to a recently replaced clutch and flywheel.

[@Gregg0112]

When you removed your fly wheel there is a reluctor ring that is sandwiched between the flywheel and crank. The crankshaft position sensor reads off this. If you had no codes before the job likely your need to reposition the wheel.
