I drive a 2011 Honda CRV which has a little over 220k miles on it. Several years ago I had the catalytic converter replaced. But now my Check Engine light is on and I'm receiving the P0420 code. Are there any less expensive fixes besides replacing the cat. converter?

Is your engine burning oil and damaging the converter? Did you check out the other possibilities that can cause P0420 the last time?
