Where is the temperature sensor on a 2001 Mazda miata?

On a 2001 Mazda Miata, the temperature sensor, also known as the coolant temperature sensor, is located on the engine block. Specifically, it is typically found near the thermostat housing, on the cylinder head. This sensor monitors the coolant temperature and sends the information to the engine control unit (ECU). If you're looking for it, you may need to access it from the top of the engine bay.
