How To Replace an Oxygen Sensor in Your Maserati GranTurismo | Step-by-Step DIY Fix

In this video, we tackle a check engine light issue that turned out to be a faulty bank 2 rear oxygen sensor. We walk you through how to diagnose it with a scan tool, then dive into the tools you’ll need and step-by-step instructions on how to replace the sensor. We also share some handy tips for getting the old sensor out and making the replacement smoother. Finally, we clear the code and go over how to complete a drive cycle to ensure the new sensor passes the OBD2 monitor checks.

Here’s a few suggested tools and parts for the job. I realized later in the video that ratcheting wrenches for the bolts on the frame underside were better suited than the 1/4 deep-sockets. Opt for shallow 8mm socket instead If you don’t use the ratcheting wrenches. You still need the 10mm deep socket for the brackets by the A/C compressor area.
