Does anyone know which sensors are which (ie; bank 1-sensor1), as in right/left or front/rear? These are the codes I'm seeing. Thanks?

1. 16514 P0130 O2 Sensor Circ.,Bank1-Sensor1 Malfunction

3. 17509 P1101 O2 Sensor Circ.,Bank1-Sensor1Voltage too Low/Air Leak

4. 17514 P1106 O2 Sensor Circ.,Bank2-Sensor1 Voltage too Low/Air Leak

And then there's this one, I have no idea what to think. Fuel air ratio maybe?

5. 17658 P1250 Fuel Level Too Low

Bank 2 the drivers side. Sensors #1 are in the front, #2 in the rear.
About that air leak, how do your vacuum lines look? Check for any frayed/disconnected lines, that is most likely giving the false air codes.

Check the connections to the plenum and throttle body first (I had a disconnected line there that gave a similar code).

If your vac lines are old and crusty, do replace them. Clear the codes and see if they come back. I bet you will be home free after that.

I'm in the process of procrastinating going to the garage to deal with that. When I run out of other things to do I will test the EGR valve itself (I've alredy replaced nearly all the vacuum lines under the hood and removed TB and cleaned EGR passage) and buttoning things up.

the vacuum lines in general, not just the EGR. But, as you stated above, you replaced them. So clear out the codes and see which, if any, return. If the O2 sensor codes crop up again, it will then be time to test and/or replace the bad sensor.

Could the O2 sensor codes be related to the EGR system problems?

Dunno. I guess we'll find out. ;-)
