Bank1 Sensor2 Where Is It?
Check engine light came on and stopped by the local autoparts store to get the error code.
Code: P2270
Bank1 Sensor2 fault
Where is this O2 sensor? I've replaced O2's on other cars I've had and just want to make sure I replace the right one.
Thanks!

Need more information
Is the vehicle in question equipped with a V6 or 4 cylinder? If 4 cylinder, it will be the sensor that is downstream of the catalyst. If V6, it will be the downstream sensor on the rear bank of cylinders (where cylinders 1, 2 and 3 are situated). As a matter of fact, another name for downstream 02 sensors is catalyst monitor sensors.

Find the exhaust manifold where it comes out of the engine. There should be a sensor right there. That's the upstream sensor. Next comes the converter, there will be a sensor after it. That's sensor #2. There might be another converter, but since the information provided about your vehicle is insufficient, you will have to go out and look at it yourself.
Be aware that a fault code does NOT mean the sensor is bad, it means there is an issue with the signal or the circuit which may or may not be caused by the sensor.

thanks all
Thanks again for the help. Replaced and fixed issue.
Just to note if you are little over weight or weight lifted then you might have to put up ramp to get to.fortunately dad's driveway is incline so moved to be able get under.
This is down on passenger side following the exhaust system about midway...but you won't see it unless looking from drivers side as plugs in from top into cat...
As others I've done on other vehicles these may be little tight to undo....this one was so rusted had to bang vise grips with hammer to start untwist.
Again love Amazon now even with overnight Sat shipping was still half price from auto parts store...
Also I always call Bosch to get right part number for sensor/vehicle as a lot times get quoted different part number from different auto stores or even sales clerks.
