2007 v6 ford escape, got code p0141 changed the bank 1 sensor 2 02 sensor but engine light stays on even after reset, checked wires for cuts or burns didn't see nothing any help is appreciated.

dont know lots about this witout engine size but some have 1 coil per cylender possible coil is bad or plug 02 sensor will cause some problems but a miss fire will cause it to run like trash

Bank one is toward the front of the vehicle. Sounds like the heated oxygen sensors have gone bad. The Oxygen Sensors are located in the exhaust pipe and require a special socket to remove and replace.

B1 means the sensor is located on the same bank of the engine that has the #1 cylinder. B2 is located on the opposite bank.
S1 means the sensor is located BEFORE the catalytic converter
S2 means the sensor is located AFTER the catalytic converter

You didn't say which engine you have, so I've included the diagrams of both 4 cyl and 6 cyl so you can see the banks

after the catalytic converter on the driver side in the exhaust pipe.

Testimonial: "Awesome info. Thanks!"

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....
