Ignore 15 and change the crank sensor - 19.  Only buy genuine vauxhall crank sensor.

When the crank sensor faiils it usually brings up a few random codes as well.  Very unlikely you will need to do anything else after changing the crank sensor.

If the revs are creeping up and you are sure it's not the ICV - might be worth cleaning and then lubricating again, then you most likely have an airleak somewhere.  

First port of call is to change the crank sensor - it can bring an array of strange problems when it fails.  Still very much doubt that you need to worry about the CTS.

Whats not clear in the guide is that you have to re-route the wiring loom end of the crank sensor wire  to exit the cable tray through one of the slots about half way along the tray.

Take the top off the tray and trace the sensor wire back from the connector, freeing off any tape etc holding it in place. There is a suitable exit hole in the tray near the idle valve cable exit, bring the wire out of there and across to the aircon pipe which is where the wire from the sensor should reach if you follow Marks guide.

With the cable re-routed it should run a lot cooler and be less likely to fail in future.

Has the engine management light gone out or is it still lit?
