Not oxygen "sensors," but, specifically, a lean shift monitoring code for the upstream oxygen sensor on Bank 2, which would be the left bank, or driver's side. This could be caused by a faulty, upstream oxygen sensor on Bank 2, but this could also trigger because of intake leaks, faulty fuel injector(s) or low fuel pressure. Also note that if there is a charging system malfunction, it could trigger false codes, so I still wouldn't rule out a charging system issue. If you do replace the oxygen sensor, I would recommend NTK or Denso brand.cmsjr9991 wrote:The code I pulled is p1163, so oxygen sensors
