Not listed for GTA, is shown for A610 but I've never seen it fitted to any.Comes up on Eastern European sites ,temp sensor .Doubt it is really needed as ECU won't take much notice I suspect ......
Part # 60 01 025 268

I guess the Japanes have rebuild the Alpine in Japan...? the country code for the car is "100" France.
Parts from the 610... in year 1989? Does anybody nows what happen if I remove the ECU?
