Holy Smokes, Thanks for sharing!!! I'm working on 2013 BRZ having same issue (P0021) after my coworker replaced all timing components.

Thank you for sharing!

Thank You. What I needed to know.

Good info. I have been thru this as well

Got a 2006 Subaru Tribeca with P0016 & P0018 and it's a nightmare. I did an engine oil flush, fresh oil, new filter, replaced the valve oil solenoids. CEL came back after 30 miles if that. I only have a basic Autel MaxiLink to read/reset codes, but nothing fancier. Was going to sell the car but now it's hopeless without dumping a bunch of money into it which I don't have. I can replace the camshaft/crankshaft position sensors but after that, if it doesn't resolve, it will be most likely a chain/guide/sprocket.

Got code p0016 and that piece on the intake sprocket also fell off when i took it off, so we replaced that sprocket. Inspected rest of timing components which all seemed to be okay. After replacing sprocket and checking timing, Now we get p0017 for the exhaust side. Could the exhaust sprocket now be sticking ? Any help is appreciated .

What does this sticking sound like? Would there be a ticking noise coming from the sprocket?

I resealed the cam carriers, valve covers and timing cover and now I have rhe P0018 code. Scanner says the bank 2 intake cam is at 22° advanced all the time. The other side does change but just a few degrees either way. Swapped all of the sensors and no change. I'm 100% the chains are on right but the arrows never lined up on the drivers side. Not sure which way to go with this now. Lol any ideals?

ummm if the cam arrows didn’t line up then it’s not timed right 🧍🏻‍♂️ they have to line up pointing at eachother

Wow thanks . I did Have this problem with a FB !!! Also ? The FB I did chains on , each phasher 3 little 1inch arms mounted on front of each exhaust & intake phaser I never seen them are couldn't find anything about them particular phaser thanks .lmk if anyone has

Did this fix the issue

Mine did the same in the top drivers side. Also wouldn’t align unless I manual moved the face plate. Not the cam. Believe is due no oil pressure.

Are the vvt sprockets supposed to be able to turn freely without turn the camshaft?

Not supposed to turn freely - if they do, most likely they're bad.

Just had my first one do this to me on reassembly today . Its confusing because on disassembly, the gear feels "fine" because its already maxed out in one direction, then when you turn it the other way on assembly, oil dumps out of it and it becomes loose and turns freely by hand. Ive done about 15 J02 recalls, they are not supposed to turn by hand, calling Toyota tomorrow about it.

Update: Needed ECU replacement because the learned values on cam timing cannot be adjusted once they're out of specifications - make sure you diagnose the code correctly the FIRST time so you don't have to go back, and if out of spec, ecu will need to be replaced as well. I tried used ECU but would not read new VIN and could not get it to read keys, let me know if you guys have any solutions - I tried using AUTEL scanner and Snap On Triton - neither worked. I didn't have time to order and try Toyota Techstream off of amazon.

I work for Toyota dealer. Techstream CAN NOT reset it, neither can Subaru's system. They both note the ECM MUST BE replaced. Absolute a pitiful design on Subaru's part.

Hello. to get the used ecu working or at least starting the car. you will need to connect the used ecu to the car. On the OBD port short pins TC and CG (pin 4 and 13). turn the ignition to ON and leave it like that for 30 min. you will see some light be flashing on the cluster. after 30 min turn key to off, take out the wire from the pins. and you can start the car.

I have installed used ECUs in these after timing repairs. SSM4 will allow you to rewrite the vin.

I have a 2013 frs, with the p0018 code popping up, planning to change the bank 2 sensor a sprocket. Once I erase the code the car drives fine like the code was never there, but after around 10 miles the code would pop back up. have any tips?

You have to replace ECU due to learned values of cam adjuster sprockets, once the computer has learned a value that is out of specifications, it cannot unlearn it and will continuously set codes even with new sprockets.

@@totalupgradeautomotive7276 ahh i see, so regardless of me changing the sprockets i’m going to need a new ecu. this code came on after i switches to 5w 30 oil, so yesterday while we drove we looked at the live data of all the vvt areas and some numbers were very off of each other. we flushed the engine and put in the original 0w 20 oil and looked at the live data and everything seems within range. but the code came back on after 25 miles of driving.

since my live data looks good, do you think i should be able to change the ecu and it should be good?

You are not right that say the sprocket should stay in oil whole night ! The Subaru technical person said the TCM should reprogram for new sprocket !
