Catalyst system
Today my check engine light came on. I have a 2001 camry 4 cyl engine
auto tranny. I run the code reader and i get code
P0420. code P0420 means Catalyst system Efficiency below Threshold
(bank 1). what exactly does this means. also i live in the noetheast
we just got hit with heavy snow. could all the slush being kick up
into the car cause this problem? thank you for any help.
