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.
