Cool, glad you were able to sort it out.

 

Now if we could just come up with one of these for the CKP sensor!

 

I have to hand it to you guys, you are a mine of useful info to many on here, without your help many would be struggling for ages. Useful helpers to know.

 

if you don' mind me asking almost a year later, where can I find something like this. I have a 2004 LR Disco and my O2 sensor harness needs to be rewired because of the previous owners crappy splicing. I don' even know if the wiring is correct. I looked on the rave manual but can' seem to find the correct colors coming for the harness. 2 wires from the harness match with the connector which are the blue/white & Brown/orange I think. But the other 2 from the harness to the connector don' match. They had the green wire from the harness spliced to the red/black coming from the connector and the red/black from the harness connected to the yellow on the connector. I' almost for sure they changed the connector out probably because they broke the original. Before I splice the wires together I want to make sure they'e connected property. I did check voltage on the wires with the ignition switch on. I only have voltage on the brown/orange and blue/white. The red/black & green wire were dead. Anything would help. This is for the O2 sensor on the passenger side after the cat.

 

Go NutZ!

 

Thank you very much for this. It helps.

 

Cool. I know what a PITA it can be to fix a boogered up wiring job. Good Luck!

 

reason I was down there and just plan on replacing all 4 is because obd reader says there' no activity on all 4 sensors and I have open/circuit on 2,4,6,8 injectors. A couple other things as well but I think I need plugs and wires. But this is an awesome diagram. Where did you find it?

 

Same issue. I went to change all 4 o2 sensors and the passengers upstream harness pulled off exposing all the pens. I am going to attempt to connect it using these pics. Ever sinse its been running like crap and misfiring. My mechanic said that he fixed it but i am getting way more fuel mixture, misfires, and Lamdba codes now. I also got the code that the upstream sensors were swapped. Arent the 2 upstream the same? Any advice is appreciated.
