I have a 2010 Pro4X Xterra. It didn't pass the emissions test. I checked the scan tool code P0420. The Xterra is running great. I've seen on you tube that you can use Stainless Steel 02 O2 Oxygen Sensor Extension Spacer CEL Fix - M18x1.5. Has anyone done that to their Xterra? I changed out the Bank 1 Sensor 1 03 sensor. The code showed P1148 for the bank 1 sensor 1 02 sensor. But still getting the P0420 code. But no other code
