Camshaft position sensor is the only one that concerns me, is this just another name for the crank sensor? Also what does no signal mean, that its bust or that it may have become disconnected?

The car has this fault intermittently, sometimes it will run rough for a day or two then be fine for months, cleared this same code once 6 months ago and its never came back until now,

any advice apreciated

It may be bust or it may have a connection problem. No signal means that the ECU is not recieving a signal from the sensor. Since you know it to be intermittent, I would check the wiring and if I could not find a fault there, I would replace the sensor.

Yeah thats what ill do, next question....
where is it? lol

If the engine has a single coil and a mechanical distributor for the ignition, then it's likely in the distributor.

If the engine does not have a mechanical distributor, then it will be at one end of the head, near the end of a camshaft.
