Just replaced the two O2 sensors (Bosch) on my '96 D1 located after the catalytic converters. A week later check engine code P0430 (Catalyst System Efficiency Below Threshold (Bank 2)) popped up. Engine still runs smooth.
I cleared the code and after a day of driving, the check engine light hasn?t returned. I don?t hear anything rattling in my catalytic converters. If the code doesn?t pop up again, does that mean my catalytic converter is fine. Should I be expecting the same code to pop up again? Does this mean I will need to replace the catalytic converter on the passenger side?
Also, anybody have any experience regarding replacing catalytic converters within California since the stricter California laws became effective Jan 1, 2009? From what I understand, they need to be specially stamped indicating a specific date and model.
