Hyundai Genesis: Engine Control System / Oil Pressure Sensor (OPS) Description and Operation

Hyundai Genesis (DH) 2013-2016 Service Manual / Engine Control / Fuel System / Engine Control System / Oil Pressure Sensor (OPS) 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.

This system consists of

- the CVVT Oil Control Valve (OCV) which supplies the engine oil to the cam phaser or cuts the engine oil from the cam phaser in accordance with the ECM PWM (Pulse With Modulation) control signal,

- the CVVT Oil Temperature Sensor (OTS) which measures the engine oil temperature,

- and the Cam Phaser which varies the cam phase by using the hydraulic force of the engine oil.

The engine oil which is supplied through the CVVT oil control valve varies the cam phase in the direction (Intake Advance/Exhaust Retard) or opposite direction (Intake Retard/Exhaust Advance) of the engine rotation by rotating the rotor connected with the camshaft inside the cam phaser.

CVVT Oil Temperature Sensor (OTS) Repair procedures

Inspection 1. Turn the ignition switch OFF. 2. Disconnect the OTS connector. 3. Remove the OTS (Refer to "Removal"). 4. After immersing the thermistor of the sensor into engine coolant ...
