How many coolant temperature sensors does the Vision have?

[LeCecilia]

The coolant temperature sensor is located at the connection between the upper water pipe and the cylinder head or at the thermostat. Here is relevant information: 1. A temperature sensor (temperature-transducer) refers to a device that can sense temperature and convert it into an usable output signal. Temperature sensors are the core component of temperature measurement instruments, with various types. Based on measurement methods, they can be divided into contact and non-contact categories, and based on sensor materials and electronic component characteristics, they can be classified into thermal resistors and thermocouples. 2. The coolant temperature sensor is installed on the water jacket of the engine block or cylinder head, in direct contact with the coolant, to measure the temperature of the engine coolant. The electronic control unit detects the engine coolant temperature based on this change - the lower the temperature, the greater the resistance; conversely, the smaller the resistance. The electronic control unit uses this change to measure the engine coolant temperature as a correction signal for fuel injection and ignition timing.
