Thanks Highhorse I should have mentioned I did take it for a 50 mile run the same night and it has since done another 55 or so of mixed driving but it's still the same. I will have a look at the link and make sure there's nothing I've missed out.

Thanks again for your quick reply

 

Hi all, I've just got hold of a known working 2nd hand unit from a trusted seller so will repeat the process and let you all know the outcome. if it does turn out to be a bad/fake o2 sensor that i was sold, i will post a link for you all to avoid.

 

My Sensor 1 Bank 2 is sending an error code. Should I replace the other side too or just this one.

 

No need to...personal choice.

 

Jaginblack, you're my hero! With no Chilton's manual for this, I was about to call a mechanic when I found your post. No engine lights today thanks to you!

In my case, the upstream sensor was clocked in such a way that the rachet handles and breaker bar didn't work. Moving the crow's foot to 9:00 I was able to hit it with a hunk of broom handle with a rubber mallet to break the sensor free. This may help otheres, thank you again!
