난이도 & 준비물
증상
I drive a 2004 Ford Ranger, which I’ve had for the life of the truck. For a few years, I’ve had the CEL on more often than not, usually for codes related to oxygen sensors and cat converter. I’ve taken the truck to a couple of shops and had O2 sensors replaced (repeatedly), but the CEL has come back on within a few days. I’m not at all experienced with auto-work, but I’ve been trying to pick up some new skills (in the interest of not going broke). So, aside from the shops doing their work, I’ve personally replaced a couple of O2 sensors, one catalytic converter, fuel filter, plugs, etc. Betwee

ef0118_196648: could a faulty fuel-pump relay have caused multiple O2 sensors to fail? No. The fuel pump relay is just an electrical switch that controls when the fuel pump turns on and off. Tester

My 2005 Buick Century with 353k miles gets a recurring P0420 code, catalytic converter operating below efficiency level. Twice this year, I tried using Cataclean, but with no success. I noticed a small hole in my muffler at the seam. Could a lack of exhaust back pressure cause the CC to operate inefficiently or improperly? Can anyone recommend a catalytic converter cleaner? Or, is it all snake oil?

My Pilot is lighting up a catalytic converter code on the dashboard. My Boch Honda dealer service is quoting $1,037 for the replacement part and more than $600 for the labor. Does that make any sense? The car has 180,000 miles on it. Should I just go with non-Honda parts?
