F15 Overheating

Afternoon all,

Ive been having issues with one of my F15's. Its a 2012 and receives heavy use, however has a pretty up to date maintenance schedule, regular servicing, OEM parts, etc. Recently, it has developed a problem with the overheating alarm going off, with a good strong telltale.

When this problem began my first response was to check and clean the exhaust manifold and check for blockages, although a little bit dirty it wasnt blocked by any means. Next I checked that the thermostat was operating at the correct temperature using the pan on the hob method. No problems there. Ive dropped the leg and replaced the impellor (and given it a service while im at it, including new oils & filter). However the overheat alarm is still going off once its up to temperature.

Is there any other potential causes of this overheating? Could the sensor have failed? Im at a bit of a loss now! Thanks.
