this bank1sensor1 is a fuel ration sensor too rite? its not the same as the sensor that he replaced in the front?

I need a sensor diagram of the o2 sensors to prove my mechanic he replaced the wrong o2 sensor. I told him bank1sensor1 was the one by the firewall and he insisted it was the one under the headers in the front, he erased the cel and it came back the next day with the same code... ugh! i jus need something to show him that he replaced the wrong sensor... 98 lexus es...
