Disco II error code help

Hello,

I have acquired a 2000 Disco II with 128K miles on it. When I got it the Service engine light was on - and after checking the codes I found it had 8 codes all having to do with the oxygen sensors.

Replaced all 4 sensors and I am still getting 3 codes. p0140, p0141, and p0161.

I have checked several times to make sure they were all installed correctly and can't figure out what the problem is. I clear the codes and not even 10 miles later the service light comes back on.

I have been tinkering with cars since my first VW but the Disco II is very different creature and I really don't want to make things worse so any help will be greatly appreciated.

Thanks in advance,

Veedub3

Did you clean and use die electric in the 02 connections?

Do you have a good scanner so you can read the actual signals from the 0'2 to determine what is wrong?

But, can your scanner actually watch the 02 sensors signals?
