lots of things can cause this.

And as the sensors age the heaters inside the fail -- so it is not simply a mater of the miles.

I have the same issue and the code is stating P0420 which is the bank1 02 sensor which is the one under the drivers seat from what I am told. Got the sensor and now need to replace but have heard various about location of it. Told to check out a post in the RX section that talks about taking the drivers seat out to make the change. Is this correct? Thanks.
