The analizer guys say that bnk 1 sensor 2 and bnk 2 sens 2 are in need of replacement. I hope to do this my self and thay gave me a part # of 75-1726. Since I was not there at the time of diagnosis, could you please tell me their location?

Your vehicle's oxygen sensors are located underneath vehicle attached to exhaust system. Simply disconnect the electrical connector and screw out to replace. Bank 1 refers to the side of exhaust at which the number 1 cylinder is located. Bank 2 will be the side with number 2 cylinder..
