How many coolant temperature sensors does the Skoda Octavia have?

[CameronDella]

Skoda Octavia has only one coolant temperature sensor. Location of the coolant temperature sensor: It is installed at the position where the circulating water in the engine returns to the radiator. It can detect the temperature inside the engine. Generally, cars have a thermostat, so the temperature is always controlled at 90 degrees, which is the optimal operating temperature for the engine. Function of the coolant temperature sensor: To adjust the fuel injection quantity, increasing the fuel injection when the temperature is low; To adjust the ignition timing, advancing the ignition timing when the temperature is low and retarding it when the temperature is high to prevent knocking; To affect the idle control valve, where the ECU controls the idle control valve based on the coolant temperature sensor signal at low temperatures to increase the idle speed; To affect the EGR valve.
