I have a 2000 dakota with a 5.9 and a p0185 high voltage bank 1 sensor 2 code came up. The truck has been surging at idle and stalling while driving the vehicle and it seems to do it more often when I let my foot off of the gas or when coming to a stop, the engine just stalls out which is not a good thing when your taking a corner. Could the o2 sensor cause this and where is the bank 1 sensor 2 sensor. thanks

 

replace the sensor, its the left exhaust pipe, second sensor or furthest sensor away from the engine
