Hyundai Elantra (CN7): Engine Control System / Oil Pressure Sensor (OPS)
Description and operation
It generates the oil pressure and temperature information (output voltage) to control the pump operation proportional control valve in variable oil pump system.
It measures the oil pressure and temperature discharged from the oil pump and transmits the pressure information to ECM. The ECM controls the proportional control valve to regularly keep the discharged pressure depending on RPM.

Description and operation
DescriptionContinuous 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.
Description and operation
DescriptionInstalled on the delivery pipe, the Rail Pressure Sensor (RPS) measures the instantaneous fuel pressure in the delivery pipe.
