Is the the front or rear o2 sensor

Well I had the front replaced before j bought the truck. So I want to be sure it isn't the new one and the bad one. It's reading a fault in sensor 2 logically that's the farthest one back... right?

Yeah, I think 'bank 2' refers to the actual O2 sensor, which is in the rear. The front sensor is actually an AF sensor, but they both work off the same principle (more or less).

There is no "bank 2" or any other bank on a 3rd Gen except bank 1 since it is only a single-out exhaust.

"Sensor 2" is the rear sensor.

As I suspected. Damn guess I know what I'm doing tomorrow!

Give a man a code reader doesn't mean he know what's he's doing lol!
