Coolant Temperature Sensor/Switch

The coolant sensor/switch informs the SCC when the engine has reached normal operating temperature, preventing any changes until such temperature is reached so that proper adjustment can be made to the air/fuel ratio. The coolant sensor/switch also controls amount of ignition timing advance or retard when the engine is cold.
