I personally have had 4 different Subys which have had this code come up and in every case it was resolved with a new front sensor.

Now if you continue to run with it, you may start to burn rich, which will eventually ruin a cat.

thats why i said 99.99 of the time. Thats also in relation to ALL vehicles, not just subaru's
