I have the following code:
P1152 Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Rich - Bank No. 2.
Okay, I know the difference between Upstream and DownStream. But, I am confused on Bank 1 vs. Bank 2. I have looked around at past posts, and I read two different answers. Anyway, when I looked at the code page it says bank 2 is in the front and bank 1 is in the back. Is that right? If this is the case. I am assuming that the Upstream, Bank 2 Oxygen sensor is the sensor located next to the oil filter on the Duratec. Is that right? Anyway, that's the one I replaced.
Can anyone help clarify the Bank 1 vs. Bank 2 issue for me?
Thanks friends,
