o2 sensor diagnosed: Code P0141
Went to Autozone today and gave them the code P0141
This is what their computer printed out:
The PCM has determined that a malfunction exists in the heater circuit for oxygen sensor 2 in bank 1. (Oxygen sensor 1 is closest to the cylinder head before the catalytic converter, while oxygen sensors 2 & 3 are located further downstream and are typically mounted in or after the catalytic converter) (bank 1 identifies the location of cylinder #1, while bank 2 identifies the cylinders on the opposite bank).
If I try to replace the sensor myself, where is sensor 2 located? Do we have 2 sensors by the cat?
Thanks
