Check Engine Light o2 sensor help!

[phraza]

Hi all,
I’ve done a lot of searching and hopefully someone smart can help me

Check engine light came on. Code p0138.
Which is bank 1 downstream sensor.

My TJ is a 2004 4.0L.

But here’s the thing, my TJ is an export one down here in New Zealand and it doesn’t have the cali emission style four o2 sensors.

It has two o2 sensors further down the exhaust. No sensors in the down pipe area. Similar layout to this diagram with the last one right near the end of the transfer case:

Basically I just need to know what NTK o2 sensor part numbers to order. Looking on Rock Auto for 2004 TJs they only have the four o2 sensors and don’t have ones like what I’m after.

Anyone got any ideas? I can take pics of the actual location if that helps.

Thanks!
Fraser

Does anyone know if the current o2 sensors on the Jeep have part numbers on them? That way I can do some researching

My OE sensors have the MOPAR number stamped in them:

Oh that’s promising! Tomorrow when there’s daylight I’ll see what I can find out. Thanks for the pic!
