Check Engine light on!!!!!

code p 430 refers to catalytic converter system , bank 2---efficiency below threshold ====causes ---cat converter--wiring ---Heated oxygen sensor (HO2S in the exhaust manifold bank 2 before the cat converter)
have the cat converter checked for failure and blocking the exhaust

Uhhhh... it's under the truck... it's part of the exhaust system. You can buy one for $180-$220 from many online dealers like RockAuto

.Here's some reading about replacement catalytic converters and the law.Enjoy.

Remember that cats are made up of precious metals inside-the cheaper ones are cheaper because they are use less of the expensive materials,and your check engine light WILL come on after a short period of time with a cheap cat.

Found direct fit cats,

Alternate brand: Magnaflow 53004ca cats for the 2 upfront and used a 94006 for the center one just before the muffler.
They fit perfect and work just fine and are way cheaper than stock.
No check engine lights or anything as someone suggested, LOL! People always with doom and gloom! I never had to change an O2 sensors and the truck is running fine.

Sounds like either: 1) A exhaust heatshield is loose. They're simply thin metal guards around your muffler/CATS. If you find one loose, remove it or have it welded back on. 2) Broken motor mount. This is serious and requires pulling the engine from the car. If a motor mount is broken, the engine wont sit right and cause multiple vibrations. Hope this helped!

did you already run an OBD 2 scan?(free at most parts shops)

Check engine light comes on because engine computer has detected a fault. It could be anything, from a cheap sensor to an important component out of specifications, to a service reminder. Most shops (not necessarily Honda dealers, ) have the diagnostic equipment to hook it up to your car and tell you what is wrong, before fixing anything. Usual rates for this diagnostic is below $100, including quote for repair.

The check engine light is probably indicating a catalytic converter malfunction the Oxygen sensor that is located after the cat tells the computer if the cat is functioning properly it is possible the wire has been broken or damaged. To see if the cat is there jack up the car and look under the passenger and driver area of the car follow the exhaust pipe from the front back the first thing the pipe comes to should be the cat it looks like a muffler with a wire going to a sensor after toward the back side of it, I doubt they never installed one but I guess it is possible.

The only thing I can think of checking would be the EGR valve, a faulty cat converter or faulty o2 sensor. Converter shouldn't set off check engine light though unless it is clogged causing too much back pressure, most likely EGR Valve.

possible plugged cat. converter-muffler

I think you will find the aftermarket Cat Conv. is the source of your problem, but without hooking up to the factory test equipment at my disposal at my Ford dealer this at best and educated guess based on 20 years of emission related work, I am a Ford certified master electronics technician

If it runs good with cat disconected with out clearing the codes; replace the cat.
