I'm getting the code P0159 with a faulty 2-3 O2 sensor issue. Where is this sensor located on my car and what does those numbers mean?

Reset the code and see if it comes back. If the code comes back, the problem is more than likely the rear passenger side oxygen sensor. Check for any exhaust leaks make sure that the wiring is intact and the plug for the sensor is not damaged If you have a scanner with live data check that the sensor is creating voltage check for vacuum leaks as well.
