When the one fitted to my car I'm changing due to on going problems.the one fitted to my car is a Lucas 73355a.. which I just gave them and they have said they have one that supersedes that Lucas number ws1161 but that sensor is not listed for my 95 4.0 xjr6.are they wrong or do I have the wrong sensor fitted to my car help please confused

 

You can calibrate it against ice water and boiling water to see if part is bad .
