I have a leak in my resonator pipe, could this be a culprit?




Maybe. 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.

At 10 years old, there is a good chance the Bank 2 precat is gone. Maybe time for mileliminators.
