Coolant Temperature Sensor (CTS)
The CTS is located at the rear of the thermostat housing and consists of a temperature sensitive resistor. The electrical resistance within the CTS decreases with increasing temperature.
ECU monitors the resistance value and triggers temperature enrichment circuits (when necessary) to extend the injector's injection time during cold starting and warm-up.
