Last October (2012) the dealer (under warranty) replaced my catalytic converter because it was "clogged". Just recently, the check engine light comes on and Autozone told me the code showing was P0420. The car runs fine, but the light coming on really bothers me. (I can get it to go off by disconnecting the battery for 5 minutes.)
The codes are telling us that this system has stopped working or the sensor in the tank thinks so anyway. A simple fix is a loose or bad fuel cap - as if I would ever get that lucky! One way I knew we had a leak is because that sucking sound when you remove the gas cap to refuel had stopped happening - another clue!

It was passable though; I wonder if P0420 just takes a while to set then maybe you can pass smog test by clearing the codes, getting enough monitors ready and getting the test done before it sets P0420. There weren't even any pending codes though so idk, maybe the silicone did have a temporary effect.

Re: V8 P0420 & P0430 codes. The catalytic converters are integrated into the manifold. Typically, for these codes the catalytic converter isn't clogged, but rather it loses efficiency. Otherwise, you'd run into trouble quick if the engine can't poop out the 5.6 liters of gas it's eating per 2 crank rotations.
p0420; pending; 1 Answer. 0 votes . answered Dec 21, 2012 by Carguy1 (11.0k points) In most cases to repair this code the converter on the passenger side of the truck must be replaced. This is right at the exhaust manifold in between the 2 O2 sensors. In rare occasions the rear O2 sensor can cause the code, but most times the converter is required.
