My 04 Laredo has been throwing intermittent the P0432 code since right after I got it 2 years ago. Lately it's been on more than off so I went ahead and took it in.
The sheet I have says: P0432 Catalyst System Low Efficiency Bank 2
So I took it in expecting it needed new 02 sensors, it has 107k and I figured it was about time. The shop (a very reputable one that has done me well for years) is telling me it's the catalytic converter. What? I thought those like never went out. Can this be right? Why on earth would my catalytic converter go out anyway?
The Jeep has run rich the whole time I've had it as well, the tail pipe is coated in dark black soot. Can this be a symptom of the cat as well, or something else?
Any input appreciated, thanks!
Oh, here's the patient:
