Have you tried Google?
That is what any of us would do.

[ajm999]

Thanks for the quick reply. I did try Google but still don't quite understand the terms it describes.

Needs a new camshaft position sensor.

Tough one that...........

You have 3 codes implying you have a duff Cam Position Sensor............

Shall we try the Cam Position Sensor?

And that was without Google's help.....

[ajm999]

Thanks for the replies. If that's definitely what it is then I will order order one to replace it. Now all I need to do is find out where it is and if it's accessible for me to do.

[LarJammer]

It isn't definitely what the problem is. But is the best guess of someone who hasn't even seen the car.

[E-bmw]

Maybe you should use your google-fu & find out if it can be tested before you order a new one, the plug may have fallen out, the wire to it could have broken, all would give the same 3 codes.

Nobody can say for definite what it is without some inspection and testing, and even then it may not always be definite. Especially on something French !

This is why there are mechanics ( although I appreciate.....some of these are as knowledgeable and capable as the person posting the question here, which is not a poor reflection on yourself, just a very very sad reflection on so many so called mechanics these days )

I would always be a little dubious of generic OBD stuff too, as all too often they can be wrong or misleading vs a dealer level scanner.

But you have what you have, the cam position sensor/wiring/trigger needs investigated

[ajm999]

Thanks so much for your replies. The information is greatly appreciated. I will have to see if I can get around to finding where it is and check the area around it as mentioned. I don't want to spend a load of money on something if it's not serious or going to cause any damage.

I'm no mechanic but I am prepared to try and resolve before taking it to a garage.

This ^ IME wires can and do fail and not always obvious so some investigation is in order before you fire the parts cannon

[ajm999]

Thanks again for your input guys. I have just had another look to check the wiring but can't find anything wrong. The only problem is I can't find the location of the cam sensor on my car. Anyone give !e Amy info on how to find where it is please?

One more thing I did notice, is that when I remove and replace the oil dipstick tube fault goes away. It does return after a while though. Does this mean anything to anyone?

[liner33]

If you cant locate the sensor how have you checked the wiring ?

A photo of your engine may help but a quick google suggests its under the intake manifold and a new one is around £25 , I'm not a huge fan of "tryagnostics" but in this case I'd be tempted to try a new one

[Krikkit]

Pic of the engine might help us identify which one you have, or the VIN number.

ETA: Actually you should be able to sign up here for the parts catalogue: http://service.citroen.com/pages/index.jsp

[ajm999]

Thanks for both of those quick replies. I just checked the wiring I could see as I didn't know which it was

Here is the pic of the engine...

[Sardonicus]

Swap these sensors to see if you can move the fault from bank 1 to bank 2 with an 8mm socket and wiggle out is all you need after clearing those stored codes , then you have confirmation of the faulty sensor if it is indeed a faulty component, I have highlighted them for you , they are identical sensors, if so dont buy cheap and just replace the offender

[ajm999]

Thanks for that reply. What are theses sensors called and do I just connect the wiring as is and just swap sensors over?

[E-bmw]

Would you believe me if I told you they were the camshaft position sensors?

Yes I would, didn't realise there was 2 though and didn't realise that is where they would be

Camshaft sensor - clue is in the name really isn't it?

They are hardly likely to be located in the gearbox are they?!
