I am getting the oxygen sensor from an american site and it says the SC400 has 2 at the front and 1 in rear. Does the UZZ31 only have 2 front sensors or one rear and one at the front?

My UZZ31 has 2 single wire oxy sensors which I just replaced from EBay Australia using a universal single wire oxy sensor (very cheap). The SC400 is an American version of the soarer that we don't have here even though many are labelled that way, really they are soarers, relabelled unless someone has imported one from the U.S. The U.S. has different legislations with regard to pollution control, which includes different oxy sensors, usually 4 wire ones. Hope this helps Cheers John

Oh sorry Phil so the back ones are for ex temp only, someone with a late 32 s2 engine was telling me the one at the back was checking the o2 after the cat.so i have only got to replace two one day thank god.

Some how you will have to keep the 4 o2 sensors, as i belive one checks the other ?? on a single pipe just put the rear left and right together in the pipe the first two need to go as close as you can to the four into one branch , let us know how you get on as we have a few late model owners on S.C.

Bit more info..the two on the L/R ex manifolds are main oxygen sensors, the next two L/R just before the cats are the sub oxygen sensors all four are heated.
