Land Rover Discovery 3 (LR3) Oil Temperature Sensor Replacement

The joys of owning a Land Rover Discovery 3 mean that there's always something broken or falling off requiring a repair. Here's my quite boring middle aged guide to replacing the oil temperature sensor.
DTC code - P0199-27
Engine Oil Temperature Circuit Intermittent

Hello Alex, I am a mechanic for a small car dealership in Foley, Alabama USA.
Thank you for making this video, it helped me with this LR we have here.
Take of yourself; and God bless.

Having issues at the moment with horrible Missfire on coldstart until car has some temperature in it, possibly same problem? Sweet as a nut when coolant is 60/70c

Hi, my temperature sensor was reporting odd temperatures like -19C. On a very hot day it seemed to trigger limp mode. Cooler weather not so bad!
In addition I also had a low pressure fuel warning, which seems to have been rectified by replacing the fuel pump. The engine has since been behaving, no more codes on diagnostic tool.
So I'm not sure about your problem, there are lots of things you can check.
Fuel filters, vacuum leaks, injectors etc...
I find I have to consider a whole bunch of stuff each time an issue arises, work backwards to eliminate possibilities and then give my conclusions a try. Unfortunately Discovery is a complicated beast!
