Checking the condition and repairing the oil pressure sensor (Hyundai Accent MC)

1. Use an ohmmeter to check the circuit between the terminal and the sensor body. If the circuit is open, replace the sensor.



2. Insert and lightly press a thick wire into the sensor channel. Check the circuit between the terminal and the sensor body. If the circuit is shorted, replace the sensor.



3. Create a vacuum of 49.0 kPa through the oil line hole and check the sensor circuit. If the circuit is open, it functions normally. Check for air leaks. If there are leaks, this means that the membrane is damaged and the sensor must be replaced.
