When I bought my car it had a code P1647 I think it was... anyhow it was a code for an upstream O2 sensor..

I see them listed from $89 to $500 ... I do not want to spend money I dont need to. What brands are you guys buying and how are the working out for you??

 

Someone has to have replaced this part... Any help would be awesome

 

Fortunately I have not had to replace any of mine yet on my Jag, but on another well know Japanese vehicle that I own starting with and L, I replaced the sensor with the OEM sensor manufactured by DENSO and have been satisfied with it. I did not want to purchase a generic and have to modify the connectors. I see that DENSO is the OEM for my 2004 Jaguar as well, at least per Rock Auto.

good luck

I ended up finding a jaguar parts dealer in California. Got a used upper control arm with a perfect ball joint and perfect bushings for $100. Also a used O2 sensor for $75. They actually sent me two for $75 bc they didnt have marked which was upstream and which was down stream. Any how, it seems like a good source on parts. Their number is 916-858-000
