  19. Corolla 9th Gen/1st Gen Matrix (2003-2008)
    I got a P0135 error code on my '03 Matrix XRS for the upstream O2 sensor. I have the replacement part but I cannot for the life of me find the location of the sensor. I think the XRS upstream sensor must be in a different location than the base model. Anyone have any experience with this? Thanks.

    Should the O2 sensors be replaced as a service item after certain mileage or years ? All of them ? The Mercedes forum suggests that new O2 sensors be used after 100K miles and I was wondering if there is such an interval for a Camry LE.
