The article suggests you can use a 2.2 ohm resistor to double check that it is a faulty sensor.

Once sensor is replaced does it need to be coded into car via star or xentry?

Did you manage to sort this one?
Hello Tony I'm in the monitoring stage at the moment however after wiping the codes a good few times the issue has now subsided, due to the numerous faults on the car perhaps the system was very dirty or caked up as first fault was dog blocked at 316% once I got regen then I had the air leak code which was a split intercooler hose (due to the split hose it was running rich and not letting dog regen) so after dpf and split hose fixed I had the exhaust gas temperature sensor code however with some driving and clearing codes etc I've driven 200 miles without limo mode and dpf is performing regens as it should so fingers crossed it's now fixed
