Comments about Denso Oxygen Sensor - Direct Fit:

Bought because of the Denso name and reputation. Hope this takes care of having the check engine light going off! I'll have to wait and see, because you are supposed to have a bit of a driving cycle. It seems to have helped already but I'm going to reset the light after wale and see if it comes back on. Will be checking to see if my mpg' s increase too?

      Is the Denso part #234-4601 O2 sensor the downstream replacement for 2004 Honda Pilot?
      I see part #234-4728 is noted as upstream replacement.
