Kia Stinger (CK) 2018-2023 Service Manual: CVVT (Continuous Variable Valve Timing) System

Description and operation Description Continuous Variable Valve Timing (CVVT) system advances or retards the valve timing of the intake and exhaust valve in accordance with the ECM control signal which is calculated by the engine speed and load. By controlling CVVT, the valve over-lap or under-lap occurs, which makes better fuel economy and reduces exhaust gases (NOx, HC) and improves engine performance through reduction of pumping loss, internal EGR effect, improvement of combustion stability, improvement of volumetric efficiency, and increase of expansion work.

Kia Stinger (CK) 2018-2023 Service Manual: Fuel Pump Control Module (FPCM)

Description and operation Description Installed on the righthand side of the fuel tank, the fuel pump control module (FPCM) controls the DC motor mounted inside the low pressure fuel pump. The module compares instantaneous fuel pressure information measured by the fuel pressure sensor (FPS) with target fuel pressure information provided by the ECM and generates the desired target fuel pressure by controlling the fuel pump motor and regulating fuel flow rate in the low pressure fuel line between the low and high pressure fuel pumps.
