I got these on a diag check:

17606 -Oxygen Sensor Heater Circuit: B1 S2: Electrical Malfunction P1198 - 35-00
17607 -Oxygen Sensor Heater Circuit: B2 S2: Electrical Malfunction P1199 - 35-00
16544 -Oxygen Sensor B2 S2: No activitiy P0160 -35-10 - - - Intermittent

Is there a fuse that could cause both rear 02's to show up like this or maybe a single wiring harness that could be the fault? I've got an appointment to bring her in but am pretty mechanical and would prefer to take care of this on my own if it's easy enough.. Part#'s for the rear 02's would be great..
