JA: Thanks. Can you give me any more details about your issue?

Hello, thanks for posting The P0021 code indicates that the timing is too far advanced, it can mean that the timing chain may be slightly off in relation to the crankshaft so the timing marks may need to be rechecked, also check that the oil control valves for the VVti are connected and the connections are good, I think it's also possible to reverse the OCV connections between bank one and bank two, let me know how it goes.

I think it is the timing chain off. IS there a manual I can use for calibrating the timing chain?
Expert:  Ted Ritter replied 8 months ago.
The chain arrangement is a little involved , the absolute best recommendation I can make at this time is to go by the factory illustration and text, I don't know how reliable the aftermarket manuals are,. Go to Toyota's tech information system directly at techinfo.toyota.com, for about $15.00 you can download anything you want for 24 hours you can print it and use it and take your time. You can try to google 1GR-FE timing chain related topics, there may be something there you can use, I can not upload Toyota's proprietary information which is against copyright laws. Best of luck.
