Toyota Repair Problems? Ask a Mechanic for Answers ASAP
What year and model are you working on and what engine does it have?
What is the mileage on it?
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?
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.
I have to go offline for about two hours, will check back with you then.
I'm back online, let me know if you need anything else.
