Hello, there's is a code of P0A2D, when the vehicle was scanned. I have tried to find it, but I couldn't get the location. Please could you help me with location, circuit diagram and how it can be tested?

Yep, the engine coolant temperature sensor is in the top of the thermostat housing, and the Drive Motor A temperature sensor is in the images below, here is the location. Please let us know if you need anything else to get the problem fixed.

Thank you very much.
It is "Drive Motor A temperature sensor" not Engine coolant temperature sensor. It seems that the information that I gave earlier was not comprehensive enough.

Hello,

After removing the inverter, I was able to access the temperature sensor as described on the diagram. It was found that one of the wires is broken and no longer connected. Fixing the wire resolved the problem. The temperature code didn't show up again without even erasing the code.
Thank you very much.
