My Pathfinder will likely never will any awards for fuel economy. However, I thought I would look into it. Plugs are like new, air filter new, oil changed, tires inflated. Hooked scan tool up, and see Bank 1, sensor 1 switches between .2 and .875 volts. Bank 2 sensor 1, switches between .48 volts and 1.25 volts and never goes below .48 volts. No codes or MIL's
Can I assume bank 2 sensor one is lazy, and not giving me optimum fuel economy, or is this too simplistic? I have not had time to look at fuel trims.
