My wagon has been having this for a while
the book says it has something to do with the oxygen.
Oxygen sensor warning
"The light comes on at 30000 miles, If it comes on have your toyota dealer inspect the oxygen sensor and reset the warning light for the next 30000 miles. Continued driving have an adverse effect on the three-way catalyst
Ive gone to 3 mechanics and they don't know what the light means lol
So anyone have any clue and how to fix and reset the light
and what the bold print means?
