Per TSB, some causes of P0430 �?· Malfunctioning ECT/CHT �?· High fuel pressure �?· Damaged exhaust manifold �?· Cylinder misfiring �?· HO2S wiring concerns (shorted or chafed, bent pins, etc.) �?· Damaged exhaust system pipe �?· Damaged muffler/tailpipe assembly �?· Retarded spark timing Damaged Catalytic Converter: �?· Use of leaded fuel �?· Oil contamination/consumption �?· Silicone contamination (sealants/cleaners) Bank 2 precat (O2 sensor) is next to radiator. http://www.contour.org/ubbthreads/showflat.php?Cat=&Board=v6maint&Number=1012316&fpart=1&PHPSESSID= At 10 years old, there is a good chance the Bank 2 precat is gone.
