Did a motor swap on a Prius, runs fine now but has code P0A2D. I checked the harness/connector going to the temperature sensor and it’s plugged in but showing code. Do I have to replace the whole transmission module?

I would check the coolant in the inverter system, and make sure the coolant pump is running. If you have air in the system, it will set this code, the temperature sensor is built into the large electrical motor inside the transmission. Recheck the electrical connector at the transmission to make sure none of the wires have pulled out and that there is no corrosion on the terminals.

Can I ask if this problem was present before the work was done? Here is where you can check the coolant level. Check out the images (below).

The problem was not present before, I checked the connection on the no. 1 temperature sensor and 2 of the wires were pulled out of the connector. Going to fix that and see if that fixes!
Thank you very much for the fast reply and amazing advice!

You are welcome, if the wiring has pulled then it sounds like you may have found the problem, please let me know if that fixes it :)
