- 2013 Explorer Limited
Been away from the forum awhile. In that time I traded in my 98 Sport for a new 2013 Limited with the 3.5L Ti-VCT V6. My 2013 now has about 141k miles on it. About 4 months ago I got the P0420 code. In the last month it has been joined by the P0430 code. No other codes have surfaced nor any issues with the engine performance that I can detect. Spark plugs were changed at 120k miles. I’ve cleared the codes and they consistently return. Used my scan tool to graph the voltage of both downstream O2 sensors and both waveforms are oscillating up & down in a manner that would indicate a failing cat. Gonna snoop around a little more first but, assuming the cats need replacement, has anyone done this job? I searched and searched and could not locate any practical advice for this generation Explorer.
The FSM gives only the obvious steps (remove 02 sensors, remove heat shield, disconnect Y pipe from converter and move Y pipe aside, remove 6 manifold nuts and then the converter/manifold). Sounds way too easy! As I visualize the steps from above and underneath the vehicle, it just does not seem possible that there is enough space to R&R the cats without removing other (maybe major) bits and pieces. Can anyone offer any tips or more detailed guidance? If I get the confidence to tackle this job, I’d be happy to take pictures and post back to the forum.
Thank you! -Mike
