Been working on the son's Rover, trying to eliminate ta plethora of codes. While installing all new O2 sensors, I see this plug on the right side of the transfer case not connected to anything:
Can't find anything that it connects to? Looks like it's wires run to the rear of the vehicle, but can't tell where. Not an easy place to see or feel around either. Oh, and the prior owner had the trans rebuilt last year---most of the wires have been ripped from their mountings and are just hanging loose.
Second question: replaced ALL FOUR O2 sensors with new Bosch sensors. Previously had fault codes for both upstream sensors. Now the Bank 1 upstream sensor reads ZERO! I made sure the connector was very clean and also sprayed full of quality electronic cleaner. Here's what the Ultragauge shows:
Any ideas welcome. Thanks
