    Check engine light has turned on during the past three winters only when under 20 degrees always the o2 sensor ? Usually turns off on its own when whether warms up. Now being the fourth winter heck engine light has not turned off and still presenting o2 bank 1. Will install new o2 sensor asap

    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...

    Check engine light on after car in driveway over night. Local dealer reported O2 sensor. $150 part and $64 for labor. Not under warranty as/dealer.

    Changed cat 3 times. Seems to get check engine light more frequent after changing cat. Going to look at o2 sensors next. Have to get it fixed for California smog check due.

    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!
