2015 Legacy - Camshaft Position Slow Response (P000A) fault keeps happening...

[das997]

I have a 2015 Legacy with a problem that's becoming more and more frequent. About a year ago, I had a random "everything on the dash lit up (check engine, park break, ABS, everything) while driving on a freeway. My brother is a mechanic/inspector and he read the OBD codes - came up as P000A ( "A" Camshaft Position Slow Response). Got an oil-change, reset the codes, and all was fine. Then it happened again in about a month. Then again 6 months later. Now it's happening every few days, mixed in with the odd U0073 (Control Module - Data Bus Off) error. He's advised me not to take the car back to Subaru until I can reliably replicate the error(s). Till now, it has happened while driving, while parking, while going over a small bump in the road, in general unpredictable.

Any idea what this might be or how to troubleshoot? I'm not really concerned about the P000A error, as it really doesn't affect anything and won't destroy the car.

Help!?!?!

I have a 2015 as well, with the 3.6 engine and I'm getting the P000B code. I need the location of the rear sensors to change them.

The A/B/C/D codes correspond to which sensor is affected. Do a YouTube search for Subaru P000 and you can see the location(s). Here are the notes I wrote about the fix:
12/28/2020 64300 Parts for P000A Code: 1 x 10921AA231 Oil Control Valve Assy + 1 x 806944060 O-Ring $176.82

U0073 requires a scan tool that works with SSM

Look for loose / dirty / damaged / oxidized connections. Inspect ALL the ground connections and straps.
Test to find one or more control modules not recognized or not communicating on CAN (Controller Area Network).
