check engine - p0141 Bank1 sensor2

Check engine light is on, error code is P0141 Bank1 Sensor2. I had Auto Zone pull the code and have replaced 1 oxygen sensor, reset light and it is back on. I think I got bad information on which sensor to replace.

Your problem is probably solved, so this is for the next person with that code.

Sensor 2 is the one downstream of the catlytic converter. As indicated at that link I posted, the problem could also be with the O2 wiring, so check that too.
