MY99 UK turbo.(bog std no mods)

Above codes have come up. The check engine light illuminates at low revs only (so far). I have reset the ECU but they came back after a bit of driving. Car seems to be running ok with maybe a little bit of a lumpy idle when cold.
Code 11 - crankshaft position sensor
Code 12 - starter switch
Code 22 - knock sensor

I'm not a big believer in co-incidences so I reckon there must be a common link somewhere but reading through the diagnostic stuff I have doesn't throw any light in my direction.

Has anybody have any experience of these? Any advice would be mucho appreciated

Thanks Pat

possibly an earthing problem.. check the earth connection on the inlet manifold just in front of the intercooler.. to the right of the coil pack..

also worth running a new wire from battery negative to the block and to the body work to see if it helps..
