Mods I have are accessport and turbo back exhaust. The code from the ap is p202 ocv solenoid valve signal a circuit open bank 2. Sorry I typed it wrong on the original post

Hi,P2092 is bank 2 intake oil control low input,in most cases the valve is the cause,other causes are low oil level,incorrect cam belt installation or clogged oil passages,there is also a possibility the intake gear is the fault.For starters which side did you replace driver or passenger,thanks

Customer: replied 1 year ago.
I replaced the drivers side intake solenoid and the code came back again right after. Brand new part from subaru and didn't do anything. I wanted to check everything before I take the car in for work. Don't really wanna have to take off the parts to go back to stock so I don't get my warranty voided
Expert:  tamaz replied 1 year ago.

Just to be clear, the valve replaced is the one on top of the valve cover, blue connector,10mm bolt holding it in, about 6 inches long

Customer: replied 1 year ago.
Yup. Right over the oil filler neck
Expert:  tamaz replied 1 year ago.

Ok,great .The cause most likely is incorrect cam timing(belt off a tooth)clooged oil feed to the solenoid or the gear itself.Are you still in warranty?

Do you think it ok to drive for a couple days while I get some time to take the mods off? I don't beat on the car and haven't had it see boost since the cell came on

Your going to need to get it back to stock,you can do this with your access port right?To correctly diagnose this we will need a snapshot of how these valves are operating through the ecm to determine the cause, dealer has equipment to diagnose it's tough to determine without being able to view data.

I wouldn't worry about the exhaust just the tune,it's o.k to drive as long as its not running to bad,the C.E.L hasn't flashed has it?

Customer: replied 1 year ago.
No. The cel is just on. Car isn't in limp mode. It runs just as it did before the light. There's no drivability issues that I can tell
Expert:  tamaz replied 1 year ago.

sounds safe to drive

Customer: replied 1 year ago.
The banjo bolt on top of the solenoid. Does that have a screen where something could get trapped? I was going to take it off and check it but theres a heat shield in the way right on top of the bolt. Could that be a cause? Also I'm just about due for an oil change anyway, could viscosity of the oil itself be a factor?
Expert:  tamaz replied 1 year ago.

No filter in that banjo bolt,there is a filter in back of the head that feeds both the turbo bearing and valve usually if its clogged the turbo will go first,oil level and viscosity could be a cause .
