    i found the reason for that no ohm reading. downstream sensor was in two pieces basically. but still have heater issues on b1s1 b2s1.

    also, any idea what radio module needs replaced? or is that the entire RNSE unit?

    Something strange going on there. Faults are for Both Banks S1 and the value of B1S2. With that said, your voltage is quite low. I'd charge or replace your battery, replace the B1S2, clear the codes and then drive it and see what comes back.

    replaced sensor b1s2, getting ohm reading now.

    still with the heater circuit on banks sensor 1. i have ordered set of 4 for backup. just wondering if i should go drive it for a bit or not waste my time and replace first.
