Hi Everyone, So I have a 1995 XJS that had a O2 heater circuit code so I replaced all four o2 sensors then cleared the code. After running it for a few weeks I am having trouble getting all the the monitors to run, the o2 heater monitor ran fine so I'm pretty sure that is fixed but i cant get the Air injection, o2, and catalyst monitors to run. Any help would be greatly appreciated

 

Welcome to the forum BurnsAF,

You've posted in the X351 (the XJ12 tech section) but refer to having an XJS.

Typo in your thread title or posted to the wrong section? Let me know which it is and I'll edit or move as appropriate.

Sorry I posted it in the wrong section it is an XJS

 

No problem, I'll move you on over.

 

Are there adaptations that need to be reset?

 

Really nobody knows not one reply?

 

Patience young Jedi; some of us have older models without catalysts and O2 heaters and such stuff so some of what you write is a bit meaningless to me at least.
Is it a 4 litre or a V12? (did they do the V12 up to the end of production?).

 

It's a 4.0L

 

In that case I would try the X300 forum, same engine. But do explain why you try that instead of the XJS forum.
