sometime ago hit a bad chuckhole , service engine light came on ..code PO136 bank 1 sensor 2 ...... have any of you ever came across that code ? & if so where is bank 1 & sensor 2 .... drove it up on ramps & nothing looks broken as in the wiring harness .....thanks in advace ..PS 130,000 miles seems to be running fine

The O2 in question is the passenger side downstream (the 2nd one, after the cats). The car will run normal with that code, as that O2 is simply monitoring if the cats are functioning correctly. You probably just need a new O2 sensor.
