My Check Engine light came on and the code says:
P0420 "Cat. System below threshold in bank 1 (Bank 1 identifies the location of cylinder #1, while bank 2 identifies the cylinder of the opposite bank)"
Well I suppose that the Cat might be getting clogged up so I'll check that.
But what does this mean: (Bank 1 identifies the location of cylinder #1, while bank 2 identifies the cylinder of the opposite bank)
