Engine Over Heating, WP or Temp Sensor?

My car as about 110k (kms) N55 2010

So today driving to Toronto the car started losing power. So I stopped turn off the engine for 3 mins the drove again then after 30 mins or so it gave the message again. I turn the car off for 1 min then drove and it didn't show again. Mind you I arrived at my destination. (Waterloo to Toronto).
Coming back to Waterloo from Toronto, I had to stop twice, I actually stopped 3 times, the second time was at a the Service Centre tired to be proactive, stopped for few mins then drove, but few mins later warning came! So it didn't really help. It seems I just need to turn off and on the car then it good to go again.

Just wondering if this is the temperature sensor or the water pump?

I also noticed sometimes in the past 2 weeks when I shift from 2nd to 3rd the care "chokes" a bit. It doesnt happen all the time though.


I got the Engine Temperature is High and the later the Engine Overheated.
The temp gauge never go pass 120C which is the middle.

A simple pull of the codes will tell you everything you need to know, more then likely its the pump. Since your in Canada you should specific KM or Miles.

The temp gauge is OIL, not coolant - reading different things.

There are multiple coolant temperature sensors, there is one water pump. Calculate the odds of what has failed.
