This morning my wife took my Tundra out to the post office and got about 1-2 miles when the Check Egine light came on. She turned around and came back home and I took my 2001 Tundra 2WD SR5 AccessCab to the nearest Toyota dealership's service department.
An hour and a half later I was informed I was ready to go. When asked what happened, they said the Oxygen sensor had failed and they warrantied the repair. I asked what caused it to fail and they had no clue, but added it wasn't uncommon on the Tundra V8 line.
Since TundraSolutions does not allow non-paying subscribers and guest to do searches or posting in the Technical section of that site (I understand perfectly, as it would be a valuable resource), I am looking elsewhere.
Has any other Tundra owner had a problem with an O2 sensor, or any other sensor going out? I have about 27K miles on the truck, of which 90% are non-rush-hour interstate driving. I change the oil regularly with fully synthetic oil and performance filter and never had any problems.
Last Saturday, I got lazy and instead of changing the oil myself, I took the 7-quarts of Mobile one and appropriate Mobile 1 filter to this very same dealership to have them change it (and they did for $9.95!). I also had them rotate the tired, but they screwed that up by rotating only two of the four tires.
Just curious. No problems until after I have someone do something. Coincidence?
