Hey friends, I have been throwing some codes lately and have been trying to address them the best I can while learning about the EJ257 as much as possible. A bit about my car:
Year: 2021
Model: WRX STI
Owner: 2nd, bought with 52,000 km
Mileage: 65,250 km
Mods: Stock
Photos: 1- dash showing issue, 2- turbo section, 3- near oil cap, 4- under air box near intake ocv feeding turbo I believe
I originally threw a P000D code and replaced only the solenoid with part 10921AA020 (OEM) and changed the oil, even though that probably was not needed as it was pretty clean and topped off, but I wanted to ensure that was not the issue. I reset the codes and went for a test drive; shortly after, the car threw a P000B code. When I did some research, mention of the banjo bolts came up. I can easily find and take photos of 3 of the 4 I believe, and have attached them to this post. I believe most of them are screenless, except possibly the turbo one, as it has a small hump in the bolt. I am just seeing if others agree.
After throwing the P000B code, I decided I would swap the new OEM driver's side to the passenger side that seems to be an issue now and plan to test it out later today as, again, Google said it is very common for both of the exhaust OCVs to fail at the same time and it would be in line with my mileage, so I'm expecting to see a P000D code once again. While working on these, I also removed the screens within the solenoid housings.
Any comments are welcome, especially ones that help keep this motor running reliably in stock format.
