Hyundai Elantra (CN7): Engine Control System / Ambient Temperature Sensor (ATS)
Description and operation
Ambient 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.
The ATS is a Negative Temperature Coefficient (NTC)-type sensor and its resistance is in inverse proportion to the temperature.

Description and operation
DescriptionThe GDI injector is similar to a standard injector, but sprays fuel at a much higher pressure directly into the combustion chamber and has a swirl disc to get the fuel swirling as it exits the nozzle.
Description and operation
DescriptionPurge Control Solenoid Valve (PCSV) is a solenoid valve and is installed on the surge tank and controls the passage between the canister and the intake manifold.
