Let me check a few things and get back to you, has anything been replaced yet?

Have you tested the OCV valve by activating it with the scanner?

What does the oil look like, any chance there is a lot of sludge in the engine?

Customer: replied 1 year ago.
oil looks good and is full I tried turning the ocv valves on or off with otc scanner and i can't find ocv valves tests on scanner. i did find a section where i can turn on and off vvt sol. but it only works with engine not running. the pinpoint test says with vehicle running activate ocv and observe engine speed. The rpm also stays around 2000

Ok, the code is for bank one, near the firewall, the most common faults are loss of oil pressure to the ocv, a bad, ocv or a bad actuator gear. Keep in mind that it can also be caused by the timing belt being off a tooth on the cam sprocket. Try removing the oil control valve and activate it to see if it's even working, I don't know of another way to test it except to use the scanner to activate each bank while the engine is running.

Try switching the ocv from left to right and see if the code goes to the other side.
