No 02 Downstream Sensor 2006 F-53

[Pirate1]

Ford says there should be one in the cat. I have a top plug in the cat, no sensor. No wires anywhere near the area to indicate someone disconnected and removed. Any ideas?

What code is it?

Just because FORD says there "Should be" does not mean there is.

Plus the pre-cat sensor can be anywhere from the manifold to the cat. (But I think that's sensor 1) not all vehicles have a sensor 2.

By the way I stress the words I THINK in the prens part. I may be wrong.

I thought of that however, I looked all over the area and no harness of plugs were near the cat.
