My check light came on and when I check the code which was a p0420, Catalyst System Efficiency Below Threshold (Bank 1). Emissions Recall U67: Catalytic Converter Efficiency. This was part of the recall. Therefore it doesnat meet the CA emissions standard. It is causing my vehicle to slightly overheat at standstill. Itas hasnat been inspected yet and It has been over a month since this started happening to the vehicle.
