Check Engine light came on and Auto Zone told me a code of P0141 was the problem. What do I need to do to correct a troubleshooting code of P0141.

Hello,
The code:
P0141: HO2S Heater Performance Bank 1 Sensor 2
This code typically displayed when there is an issue with the oxygen sensor.
The heated oxygen sensor (HO2S) is a sensor designed to create a voltage relative to the oxygen content in the engine exhaust stream. The control module supplies the HO2S with signal high and low circuits. When there is an issue with the circuit it can trigger that code.
