Where exactly is the oil control valve located in 2012 subaru impreza 2.0 limited?

 

And what is (bank 1)?

 

Code P001: Camshaft Position “A” - Timing Over-Advanced or System Performance (Bank 1)

A side should be the passenger side.

 

How long since the last oil change? These OCVs need super clean oil or they get clogged or sticky and cause problems. Full synthetic oil and high quality filters are a MUST!

Oil change was done 3,000 miles ago. I took a look in the engine bay and looks like this car has 4 Oil control valves? I am still a little confused thinking in replacing it myself, but dont know which one of the 4 is actually faulty.

I agree completely about the Oil, Any conventional oil causes havoc on these. Synthetic is a MUST. The oil passages are as small as a needle on many of these.

 

In any case, here's a description right out of the FSM, and correctly identified as the passenger side ( US models that is ) and the UPPER valve, Intake for cyl 1 & 3.

 

DTC P000A A CAMSHAFT POSITION SLOW RESPONSE (BANK 1)

1. OUTLINE OF DIAGNOSIS

Detect the AVCS system malfunction.

Judge NG when the amount of intake AVCS actual timing advance does not approach to the amount of AVCS target

timing advance.

 

REMEMBER, this is just the CONTROL for the advance. The advance is really done by allowing the oil pressure into the front of the intake cam pulley. Then inside the pulley the oil pressure causes the pulley to change position relative from the chained sprocket to the attached cam shaft. So the valve may be allowing the oil to pass, but the pulley may not be advancing fast enough.
