Throttle Position Sensor

[Tronzo85]

My wife owns a 2017 1.4 Corsa which has been having engine management light popping up and it's going into limp mode.

Code reader shows Throttle Position Sensor fault codes every time however once cleared it goes away for another week or two until it's a cold morning and it reoccurs.

Initial thoughts are to replace the Throttle Position Sensor however I am finding it impossible to find this part... No site even given me a part number.

The car doesn't owe us a huge amount but we would rather keep it running ourselves than being robbed again by the garage.

Any help for part number or a knowledgeable fix would be greatly appreciated.
