They don't have a conventional CTS, its a CHT (Cylinder Head temperature) sensor and measures the temp of metal diectly and works on a NTC principle. it's on cam cover between plugs 2 and 3, if you pull this lead and turn ignition on fans should run and should EML should illuminate due to a fault being registered, when plugged back in it should rectify this if working correctly, it also controls temp gauge so if you have an abnormal reading this could be an indication.
