Where is the oxygen sensor located and is this what I am suppose to replace?
The sensor is located on the exhaust system between where the cylinder ports enter the common manifold and the muffler. Sometimes they are on the cast iron manifold and sometimes they are on the exhaust pipe after the cast iron manifold.

sounds like the transmission is in "limp"mode it allows you to drive even though there is a problem with the transmission,the code 21 is probably a transmission manufature control code and not engine go to autozone and they can scan it for free,if you just had transmission fluid changed recently if you used anything other than what the manufature calls for like atf+4 then this is your problem,flush the system and do a fluid and filter change with correct fluid as by what the owners manual,or dealer calls for,don't rely on autozone to get it right.

Okay, good, that makes it a bit easier. That code refers to sensor B1S1 or Bank 1, Sensor 1. Bank 1 refers to the side of the motor that has cylinder #1. Since you have an in-line six cylinder, that part is easy since there's only one side. Sensor 1 refers to the sensor before the catalytic converter. Since you have only one bank, and one exhaust pipe, that means its the O2 sensor before the catalytic converter.
You only have two O2 sensors, one before and one after the catalytic converter. Check the wiring and connector on the sensor before the catalytic converter and if all seems good there, then replace the sensor itself and see if that does the trick.

well first off depending on the year you could have up to four.now the easiest thing is to check trouble codes by turning yor key three times.now move it to the first position it moves to.thats were you need to end at all three times.now from that position you will move it quickly to the position when the accessories and idiot lites lite,right before it hits the starting position.so do that three times and wala if you got a problem with it your gonna know which one of the four you need to replace.follow the imortal saying of if it aint broke dont fix it ,oh ya to locate just look at other answer

Hi there, do you get water from the air conditioning unit entering the passenger foot well, if so then perhaps water is dripping onto the electrics below and causing these problems (blocked evaporator unit) alternatively, get jeep to reset your system (2 minute job) and this should work, keep an eye on it as the first new code that appears should be the problem area, hope this helps
If your check engine light is on and you have a diagnostic trouble code P0135 stored in the PCM's memory... then you've come to the right place to test and troubleshoot the upstream oxygen sensor.
The
common fix for this code is to check the integrity of
the heater wires. Check the wires for insulation and routing
which could be loose or touching a hot exhaust that can
short the wires. If the engine has too many miles, it
is possible that the heater circuit inside is worn and
shorted which needs a replacement of the oxygen sensor.
If you have a DVOM, you can also test the continuity of
the heater wires from the oxygen sensor to your computer
