Engine light came on every 2 weeks, even after the oxygen sensor (Bank 1 Sensor 1) was replaced. Eventually they found the problem to be a leaking intake gasket. Replaced it and have been driving for a week so far with no problem. However, there appears to be some leakage of oil!

P0133 error code. Had Dealer perform TSB EG017-07. Still had error P0133. Replaced bank 1 oxygen sensor. Still had error P0133. Just found TSB EG045-07, which seems to also apply, but not covered by emissions warranty any longer. Debating what to do...

according to the dealer this isn't covered under a recall nor the Fedeal Emissions Warranty :(
Cost us $432 including another diagnostic fee ($120). We'd already had the vehicle to our mechanic who had run diagnostics and had it diagnosed correctly (according to the dealer). Our mechanic thought maybe Toyota would do the repair under the Emissions Warranty. But alas the dealer says no. Lesson learned? We should always stick to our known excellent mechanic even when he tries to be a nice guy and help us get what he thought was a warranty repair. Our guy would have only charged $335 including diagnostics!
