Engine Performance problem
2005 Ford Taurus 6 cyl Front Wheel Drive Automatic 101000 miles
My MIL light is on. My OBD-II returns a PO-430 code, "Catalyst system below threshold Bank 2". I presume that means catalytic convertor replacement time. My service manual shows one dual y-shaped cat, which can be obtained from Eastern and several others for a relatively modest $300 or so. Repair shops are telling me there are additional convertors and to expect $900+ for parts, labor additional. The replacement looks like a bear of a job without a lift. Are there additional cats beyond the y-shaped one? If so, how do I differentiate which one(s) should be replaced? Is the dual y-shaped cat a bolt-in job or must it be cut out and welded in place?
Sorry! "My bad!" It's a 49 state 3.0L V-6 OHV, I believe that's a "U" engine code, but it appears both V-6s that year use the same Y-shaped cat. Can you tell me if there is an additional cat behind that? If there were an O-2 sensor problem additionally, wouldn't that show up as additional codes? Some of my monitors still do not show as "incomplete" after driving the vehicle for two or three days after clearing a code.
have the same problem?
