Denso is a great friend. I just removed one and replace it with a new one and that did the trick.

    Comments about Denso Oxygen Sensor - Direct Fit:

    Advance Auto associate told me my check engine light was on because of the left forward O2 sensor. Pretty easy to install. Saved the $75 minimum charge at local garage and only took 10 minutes to get the job done. Had to go back to Advance Auto to get my check engine light reset but no big deal, only 2 miles away.

    • Q:

      Good Day,
      There are a total of four Oxygen sensors on my 07 GMC Sierra. Two upstream and two downstream. Your description states a total of two for my vehicle, are the upstream and downstream units the same part or is there another part I have missed?

        There are 2 different part numbers for the 4 O2 Sensors used on your vehicle. My engine code showed one O2 sensor as being bad. I replaced all 4 as my truck had 150,000 miles.

        I'm happy to help, Steve-O! This Denso Oxygen Sensor - Part No. 234-4337 is an upstream sensor for your 2007 GMC Sierra. For downstream, you'll need the Denso Oxygen Sensor - Part No. 234-4651.
