well im new here but a mechanic, first off its a fuel system bank 2 sensor 1. if you or someone you knows or just bring it to the shop they should be able to watch your 02 sensors. if its a short to ground on 1 of the sensors it will read near 0 or 0 volts, or if its a short to voltage the reading will be high. try that first and let me know
