I did clean up before on the cat, but it only last for a little bit. the best way is to change a new cat convert and O2 sensor so it won't trigger the CEL.the eliminator will work for few miles, but you still will trigger teh CEL either way. trust me, i been there.



With mileliminators (installed correctly), you will not get P0420 (Bank 1 Precat) and P0430 (Bank 2 Precat) codes.

The other codes have nothing to do with the Precats, unless your precats are plugged or main cat is plugged. You might then get a P0401 or P402 because of the cat problem.




the P0420 and P0430 is not Cat converter, those two code are intake manifold. things is that i clean my before and used eliminator too, still the same code still came out.




Those are cat codes. Check this link for a list of codes:

It is also worth noting that often when those codes are sent, they are false codes. They can set when there really may not be anything wrong with the cats. There is a TSB that reprograms the PCM on some Contiques (not all, not even as many as should have been) that widens the parameters for setting the code. If you need more information about this, speak up and I'll post it again.
