2001 Subaru Outback base. Error code P0420 - Catalyst is below threshold. This error has been on and off for a couple years, and now it's on permanently. I am active duty military and my wife is busy so we haven't had time to deal with this. I know that the check engine light only monitors emissions-related things, when we got the emissions tested it passed (I forget the exact readings). Two years ago we had the O2 sensor replaced, however the dealership mechanics said that it was the catalytic converter after all, so they wanted to replace that too. We still get 20mpg and pass emissions tests though. What can I do to fix this? Thank you for your help. We also have a problem with the right rear rack and pinion rack assembly which is throwing off our alignment, but that is a topic for another post.
