Thank you very much as I'm not sure the same rule applies to the US spec.

 

Pretty sure the engine configuration is the same regardless of the driver position.
One way to confirm would be to unplug the downstream O2 sensor on one side and see which code pops.

 

It is pretty much a universal configuration for 90% of the vehicles ever made. I have never seen one that varies, but i dare not say that it doesnt or someone will argue or try to call me out.

 

Thanks.

I will try this at the weekend.. Replaced the passanger and drivers side, (Pre Cat) but the passanger side is so difficult to do as you tighten up the sensor and all the wires twist round.
Spent more time under the car than I have the Missus! Lol. She's not happy. 😁

 

When i WAS a mechanic, we normally did not hook up the electrical connection until after it was tightened just for that reason. I have never seen or worked on the D2 system so im not sure on that aspect. I know it can be a tight fit sometimes when everything is back in place.

 

There's no reason why you need to make the electrical connections before installing and tightening the O2 sensors on the D2.

 

Do not get the cheap ones off Ebay or Amazon. I have tried them a few times and they are all trouble. Denso or Bosch work every time.

 

Walker brand O2 sensors seem to be very reliable.

 

I too have had good luck with Walker.

 

Incorrect.

Bank 1 is on the left-hand side as viewed from the driver's seat, regardless of which side of the steering wheel is on. Viewed from the front of the truck with the bonnet propped open, Bank 1 s to your right, on the side opposite where the battery is located.

So another words, Bank 1 is on the driver's side on all trucks where the driver sits on the left, like in the U.S.. Bank 1 is on the passenger side in all trucks where the driver sits on the right, like in the UK.
