Question

Check engine light came on today in my 2011 Ford Ranger.  Took it to have a diagnosis ran and got a P2270 code.  It sais Oxygen Sensor Signal Stuck lean Bank 1 Sensor 2.  Where it is located and how hard is it to change out myself?

Answer 1

P2270 - 02 sensor signal stuck lean Bank 1 Sensor 2

When it comes to Sensor 2 these are catalytic monitor sensor, or the downstream 02 sensor, The location is right after the catalytic convertor. Be aware what set this code are also exhaust leak before the catalytic convertor.

​ H02S sensor downstream after the catalytic convertor, replacing the 02 sensor is not that difficult , having the proper wrench you would be able to remove within 1/2 hour
