Rear O2 Sensor Wires

ferocity02 · 08-08-2016, 05:04 PM

I changed my rear O2 sensors awhile ago and am wondering if I swapped the sensors on accident. I am getting the following codes:

2C6D "lambda probe behind catalytic converter, aging"
2C73 "lambda probe behind catalytic converter, signal"

I checked the wiring and pins at the DME and it looks good. The sensors seem responsive in INPA. I do not have DPFix installed. I do have DP's but these are not the typical DP codes.

Anyone know which sensor plugs into which DP?

Thanks!

Rear sensors only go on one way. Can't mix them if you tried. N54 335i.
