new oxygen sensor same code
got a code on a 2001 A8
17539 - Oxygen (Lambda) Sensor: B2 S1: Internal Resistance too High
I checked the wires and supply voltage as per the Bently manual
The resistants was too the high but really close on the sensor. I replace the sensor with a bosh sensor for that specific car and position. the code came back. Anyone have this happen?
Any ideas?

the latest
I cleared the code I also checked the ohms resistance on both precat sensors and they appear to be good. Remember the drivers side one is new.
I also checked the connectors at the ECM. CEL came back after a couple of days. However this time it is a different code. It is the other side ,same problem. So I checked both sensors with am ohm meter hoping I would find this one bad and found no difference. Any Ideas?
