Xantia V6 Cutting out and Starting Problems
Our Xantia V6 seems to be giving problems at the moment.
It started to be hesitant and snatching when moving off until I changed the fuel filter and that seemed to cure that, guess it was just being starved of Petrol.
Now it seems to be cutting out, the revs fluctuate to suit it's temperament and when it's remotely warm, even after running for 2 minutes it seems to refuse to start.
Tonight I just managed to coax it into starting, and when it did start it seemed like there was a plume of grey smoke from it. I ran the Lexia on it and it told me there was a temperature sensor giving a bad reading.
Only problem is it didn't tell me which one it was likely to be. Instinct tells me it's likely to be the brown sensor, is this the one that talks to the Bitron box?
Thanks in advance guys.

It won't be the brown (bitron) sensor, as that only affects the cooling fans and A/C. The engine ECU uses the green sensor (I think). A faulty temperature sensor can cause very poor running.
I don't think that either of them are easy to get at. I think that the Lexia actually tells you the temperature measured by the green sensor, so you should be able to get a "second opinion".
Was the sensor fault current, or just a stored fault?

From memory without going and checking again, I think the temperature sensor was reading a constant 30 degrees.xantia_v6 wrote:It won't be the brown (bitron) sensor, as that only affects the cooling fans and A/C.

The Green (ECU) sensor is easy enough to get to. It's the brown Bitron that's a pain..
This pic shows it, just below the lower green arrow... The original picture was done to show the bleed valve locations.
Don't forget there is also a temperature sensor on the airbox by the idle air hose...
30 degrees F or C?

hmm I wonder if this is whats causing a missfire when cold on my V6... once warmed through shes perfect through the rev range, so I cant see it being coil packs, also has new plugs...

Brilliant, Thanks Jim, I'll check this one tonight.CitroJim wrote:Lexia You have one haven't you Paul?citroenxm wrote:No, which sensor then Jim???
David, green sensor reads 2.9K at 21 Degrees...
A new one from Cit is £31.
I'll warm it up and cool it down and see if I can get a different reading from it. If I can then I'm guessing it's another wiring fault like the heater on this blasted HDi.

I do indeed...MikeT wrote: I just replaced mine on the 1.9TD but it was about 2/3 that price. Do you know the part number? It's possible they're the very same part.
Part number given to me by Citroen Glasgow was 133891.
I should also say it was £31 + VAT so will be about £38.
Are they the same between Petrols & Diesels?
