Hyundai Elantra: Engine Control System / Oil Pressure Sensor (OPS)

Hyundai Elantra (CN7) 2021-2025 Service Manual / Engine Control / Fuel System / Engine Control System / Oil Pressure Sensor (OPS)

Description and operation

Description

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.

Specifications

Pressure [kPa (kgf/cm², psi)]	Output Voltage (V) [Vref = 5.0V]
50 (0.5, 7.25)	0.3
100 (1.01, 14.5)	0.5
600 (6.11, 87.02)	2.5
