![Question](https://www.rx8club.com/images/icons/icon5.gif)
Just recently bought my 2006 Rx8. 101k miles and in decent shape. I replaced the battery today so I no longer have to jump every time I start it up, however the car idles too low and will stall unless it is constantly revving.
My error OBDII codes are as following:
Heated oxygen sensor (HO2S) 2, bank 1, heater control - circuit low
U1900 Pending fault present
[Ford: CAN Communication Bus fault - receive error]
For the oxygen sensor I’m not sure if I need upstream, downstream, or both.
As for the U1900, I need some extra help figuring out what is even causing it. What are some things I can do to diagnose the issue more specifically (and fix it)?
