I have searched and seen post that list this as either a O2 sensor problem or Cat converter problem. I want to go the route of the O2 sensor first. I know it's Bank 1 but which sensor? There is one that is before the cat and one after the cat, but which one does the error point to?
Also where after the cat is it? someone told me that it's close to the back of the car by the muffler. If anyone gets their car on a lift, can you please get a picture of where the sensor after the cat is?
