Just got my new diogmostic reader as I have an engine light come on.

Just read the codes and it's come back as a oxy sensor heater upstream cat bank 1 and the same for bank 2.

Can someone tell me what this actually means??

Thanks!
Ryan

If UK spec yes, just the two.
NAS spec have four one before and one after each cat, I believe the Japanese spec is similar but then maybe not

If you have four (check the exhaust) then you have a NAS spec engine with a few other differences.

When four are fitted, they are different types front and rear.

Finally got around to sorting this today - they really were a pain to get out. A few hours later, all sorted and new ones fitted. Running perfectly. Thanks for the help!
