Re: MIL = P0420



The dealer won't analyze it either. P0420 he will just replace the Cat. With
a good OBDII scanner you should be able to analyze the )2 sensors. For some
info read this tip http://www.troublecodes.net/articles/catfailure/

How was that tied to the P0420 code? P0420 has nothing to do with the
primary sensor.

Thanks for the reply Tegger.

Actually, it got me thinking and it seems the last time I got P0420 was in
August 2004. It coincided with some 'rattling' noise coming from the
exhaust.
The dealer's remedy was to replace two (2) exhaust 'donuts'. The car still
has
the original muffler and there is no rattling that I know of...

For now, I think I will try to find some Techron (Tactrol here in Canada)
and
reset the MIL. The cracked exhaust manifold warranty extension ran out
about 2
years ago.

Thanks again your thoughts Tegger.
