Hello! Bank 1=Left bank...Bank 2=Right bank...Looking from the transmission side..towards the drive belt side...Left bank=left...right bank=right...Sensor #2 is located behind the cat...

Sound like a DTC P0141 - O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 2)
A code P0141 may mean that one or more of the following has happened:
* open or short to ground in the wiring harness
* O2 heater circuit wiring high resistance
* O2 heater element resistance is high
* Internal short or open in the heater element
Note: Typically a failed catalytic converter does not cause this code. You're more likely to see a P0420 code for a failed converter.

SOURCE: where's the bank 1 sensor
O2 sensors location is broken down like this. The bank refers to which side of the motor the sensor is on. Bank 1 is the same side of the engine as the number one cylinder. Bank 2 is the other side of the motor. Sensor refers to either before the cat or after the cat.
Bank 1 sensor 1 would be the O2 on the side of the motor that the number one cylinder is on and before the cat.
The number one cylinder is on the back side of the motor (the side closest to the firewall). The O2 sensor will be in the exhaust pipe near the exhaust manifold.

Your first mistake is having a "diagnosis" by a parts counter sales person.
I wrote an article about his very subject. You might find it helpful. Click the link below to read the article:
What Else Could Be Wrong?
Then, you did not list the code that you got the first time, so there is no way of knowing if the parts sales person told you correctly on the first time or not.
Diagnostic Test Code (DTC) P0058 is defined by SAE J2012 as "HO2S Heater Control Circuit High Bank 2 Sensor 2" (SAE J2012 is the standard by which all vehicle manufacturers must define the "generic" or "non-vehicle specific" diagnostic test routines necessary to properly diagnose and repair their cars.)
To understand what is going on here, it is very important to understand that this code definition DOES NOT tell you to replace the oxygen sensor. This is an oxygen sensor heater CIRCUIT code. The heater circuit on your vehicle includes the battery voltage (B+) supply circuit and the heater control (HT) circuit to the Powertrain Control Module (PCM). Failure of either of these circuits will cause DTC P0058 to set.
The B+ circuit consists of the BLACK/RED wire at the oxygen sensor connector which gets its power from the EFI 2 fuse (10 Amp) located in the engine room junction block. There are several things powered by this fuse and there are several splices and branches in the wire. Voltage MUST be checked at the O2 sensor connector.
The control circuit for the Bank 2 Sensor 2 heater is the WHITE/BLUE wire that runs only from the O2 sensor connector to connector E7 PIN #33 at the PCM.
BOTH of these circuits must be check to make sure they are not shorted to ground and that they have continuity to their connections at both ends.
Also, after repairs are made, all engine control codes must be PROPERLY cleared using an appropriate scan tool in order to make the check engine light turn off and to prevent additional problems with the engine control system. Many uneducated do-it-yourselfers will tell you to disconnect the battery cables to accomplish this. That is NOT the correct way to do it, and this can cause voltage spikes that can damage sensitive computer equipment in your car and possibly cause fault codes to set in several of the computer modules in your vehicle.
Many do not believe that this is possible. If you want proof, pull the plug on your home PC and plug it back in a few times and see if it doesn't wreck your hard drive....
