I talked to the technician who is working on my car a week ago and he said the driver's side intake OCV had a cracked connector and the cams wouldn't move with techstream, so I said replace the OCV and let's see how the cams move. However, don't be surprised if the code won't go away. We'll hit rock bottom on the waterfall flow chart and it will need an ECU. I had to call the dealer (they didn't call me) at the end of the week and they got the tech on the phone. He said the cams are moving just fine with techstream and the cam sprockets are acting normal. He said he had printouts of the learn values and everything looks good except the P0018 is still present. I said go ahead and replace the $675.14 ECU. No news today (we're starting week 3 in the shop now), so I called the service desk. Code is gone. Apparently the "abnormal noise" from the engine chased it away. I informed the service writer that the engine did not have any noise before the valve spring replacement. Good thing I never took position of it. The Toyota rep usually stops at this dealer on Fridays. There's a chance he may come in earlier.
