I have a'01 disco 2 with 130k miles. When putting all new o2 sensors on the vehicle, I pulled off the right rear head of the sensor connection on the vehicle. All I have is 4 wires sticking out and I don't know how to put them back in the right order to reinstall the sensor properly. Does anyone have info on how to put all 4 wires back in the right holes when you don't know how they were in there in the first place?

By the way, the service engine light came on after I put them back together wrong apparently. I had a diagnostics done and the reading was P0157 Bank sensor to sensor and also P1590 Idle speed control. He also said it read O2 sensor Low voltage. I'm assuming this is being caused by the issue above. Any advice would be great.

TIA

Have you tried looking at the other matching sensor to see if you can figure it out?

 

Thanks Spike,

Me and Mike talked it over by phone and we think we got it figured out. Thanks for your help though.

Glad to hear it, that one is def a phone call issue.

 

A phone call issue or could use the connector view to figure out which goes where.
