I have 2008 Nissan Versa Hatchback. The MIL has recently come on and it is showing a P0240 (Catalyst System Efficiency Below Threshold Bank 1).
I know it's sometimes hard to diagnose the correct reason for this code so I have provided some data that I hope can assist with pointing to the right component that is bad. I am thinking it's the bank one O2 Sensor but would like a second opinion.
Car runs great and I have not noticed any difference in MPG or performance.
