I’m having issues with my 02 Sensors, there is only 2 on the 4.0L but there is different 02 sensors out there which ones do you recommend?

 

NTK

 

I second NTK, easy to get hold of and has been working fine for years on mine.

 

do you happen to have the part numbers for both of them?

I can find one of them but not both in ntk

2000 Jeep XJ 4.0L

 

Year would help get correct answers.

 

Just go to Rockauto and look up your year. It will list a number of options including NTK.

 

I agree with the others. NTK sensors and Rockauto.com the first stop to shop for them. NTK is the original equipment provider of the oxygen sensors on your 2000 XJ.

If Rockauto.com doesn't carry them, try Autozone......recently sourced some NTK oxygen sensors for the 4.0 engine from them.

 

Apparently NTK has the forward one but out of stock for the rear I left NTK a message to find out if and when they will be available

 

Rock auto has no NTK 02 sensors

 

Is yours Federal (2 O2 sensors) or CA (4 O2 sensors) emissions?

two

 

I can locate the downstream, however, there is no stock on the upstream that I can find

 

This appears to be in stock. If not, you may have to "bite the bullet" and get the Mopar from RA for the long term, or buy one of the cheaper ones while you wait for an NTK to become available.

If you are talking about the 23099 they look available to me.
At least online at Napa.
My store says not till Saturday.
Some of the other stores in my area say not till tomorrow or Friday.
And one has it in stock.

 

He meant the Upstream, 23506. Napa shows OOS.
