P0135 is an oxygen sensor. (Oz is actually O2, as in oxygen.) Sometimes a sensor code is not because of a problem with the sensor itself but rather because of a faulty ground or some other issue. Does anyone here know what other things should be checked before buying a new O2 sensor?

If you decide to replace the sensor you will need an oxygen sensor wrench from an auto parts store. You should also be aware that for oxygen sensors in particular there is an enormous difference in price and in quality between honda and aftermarket.
