What should Swift do if its idle speed is too high? There are several water temperature sensors.

There is only one water temperature sensor, next to the right water pipe. The problem of high idle speed depends on which engine you are In winter 1.3 engine usually starts at about 2000 rpm, and the water temperature will drop to about 800. There is no solution to this problem, and the engine itself has design problems.

If the idle speed of 1.5 displacement is high, you have to go to the store for maintenance, and the throttle is likely to be dirty.
