How many coolant temperature sensors does the Malibu have and where are they located?

[DiAbel]

The Malibu has one coolant temperature sensor, located at the connection point between the upper hose and the cylinder head or at the thermostat. A temperature sensor (temperature-transducer) refers to a sensor that can detect temperature and convert it into an available output signal. Temperature sensors are the core component of temperature measurement instruments, with a wide variety of types. According to the measurement method, they can be divided into contact and non-contact categories, and based on the characteristics of sensor materials and electronic components, they are classified into thermistors and thermocouples. The functions and composition of the coolant temperature sensor are as follows: 1. Function: The coolant temperature sensor is installed on the engine block or cylinder head water jacket, in direct contact with the coolant, to measure the temperature of the engine coolant. The electronic control unit detects the temperature of the engine coolant 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. 2. Composition of the automotive coolant temperature sensor: Its interior consists of a semiconductor thermistor—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.
