How many O2 sensors on a 2004 XC90 T5?

Post by joelq »

Hi all -

Starting to do some planning on replacing the O2 sensors on my 2004 XC90 T5 and can only find Front and Rear sensors when searching parts online. Are there only two (one before the CAT and one after) O2 sensors on this engine?

Thanks!

Just closing the loop on this - the 2.5T has two sensors - one front and one rear. I just finished replacing the front sensor and put together the write-up here. Hopefully it helps someone!
