just recently i posted a problem with toy. siena and now i have a new one with my 03 corolla code is po135 '02 heather sensor malfunction' i change the 02sensor and reset the code and it works, but that is only for a while.
after a couple of weeks the check eng. light is on again. what i did is grab my scan tool, scan it again and found out that i have the same trouble code. does this means that the o2 sensor that i got is defective? or i didnt solve
the problem?
thanks for looking
danni
