Description and operation
DescriptionAmbient Temperature Sensor (ATS) is installed on the front-end module and senses the ambient temperature. This sensor is exposed to the ambient air temperature in front of the radiator.
Description and operation
DescriptionContinuous Variable Valve Timing (CVVT) system advances or retards the valve timing of the exhaust valve in accordance with the ECM control signal which is calculated by the engine speed and load.
