DTC P1647 'O2 sensor

X300
1

Well my XJR-100 is pushing the 100k mark clocking in at 91k and I got a limp home mode switcharoo on my way home from a quick jaunt. Upon further investigation it would appear that the upstream O2 sensor is complaining. that being said; I’ve ordered replacements NTK 25607 & NTK 25702. Not happy that the clips don’t match black for downstream and grey for upstream. Is it worth emptying my pockets for an additional $350 (from the dealer) to make the clips match? I think not.

Ok side tracked again
My question is this. Has anyone cleaned the O2 sensor with any varying degrees of success? I plan on replacing the sensors anyway, but the parts won’t arrive until January. I’d kinda like to have the available between then and now.

Just curious.

Thanks Andy for the response. Too late, I’ve already purchased the NTK’s I guess I’ll just find something else to tinker with…. Umm like my old reliable XJ6
that turned me into a liar (about being reliable). :0
