Yes, when I saw that code I immediatly ordered a new ECT sensor.
Now I have to decide if I order a jag controller module and hope it fits and communicate correctly with the AM computer or try to have this burned one repair.

Honestly I would be extremely surprised if it did not communicate correctly. After all our fans use a Jaguar fan setup. Here's an example: The OE provider (Bosch) stopped making fans (and modules) in 2012 for the BMW e46 chassis. I tried aftermarket fans (and modules) in two cars and they were junk. I started using Bosch fan modules that were in certain Mazda, Ford and Volvo vehicles that carried a similar Bosch part number. I've had two in a couple of bimmers now going on 5 years - no issues. On those I had to splice the BMW harness (pigtail) connectors at all the connections cause the Mazda, Ford and Volvo used different connectors than BMW. You won't need to even do that since the fan connections are Jaguar cause it's actually a part for the Jaguar fan. The only connector that could theoretically be different is the 3-wire connector coming from the ECM - but I think the odds there are even 100/1 against cause it plugs into the same module. The inner workings of these are simple - they control fan activation and speed based upon the PWM signal (whihc is just a square wave on/off voltage signal from the ECM - all the complex logic is pretty much in the ECM.
Confirmation. The Jag fan and controller is a direct fit, and works perfectly, no wiring connector changing needed.
Thanks, That’s good to know as it likely confirms that the newer smaller fan module that replaced the original Jaguar (BTM) fan module can be a low cost direct replacement if the fanmodule only needed replacement. Takes the cost from $800 (used) to less than $100 for a new equivalent factory quality component.
It's down beneath the throttle body housing - Remove the accessory belt then remove the waterpump pulley (3 bolts) you will see the harness. If you have a workshop manual refer to page 3-3-10. Add a little coolant on the o-ring when installing the new one.
A note on this part - it is an extremely common part used on nearly a hundred Ford, Daimler, Jaguar, Land Rover and Mazda vehicles. Not sure why Aston parts dealers sell it for $240 - it's typical cost is about $12.
