Temperature sensors don't activate at any specific temperature; they're always functioning, whether the engine is cold or hot. What you need to check is the sensor's internal resistance. These sensors have ranges or scales, starting at 4.1 ohms and decreasing as the temperature increases. This affects the injection pulse, meaning the amount of time the injector is open, which in turn determines the amount of fuel injected. This is why, when they're faulty, cold starts are very difficult due to excess fuel. When the injector is cut off, it sends a starting signal of -40 degrees Celsius. Find the parameters and compare them; if they're the same, it will work. However, in most cases, they aren't generic.
