3. Replace the oil filter with a new one, ensuring it's properly tightened.
4. Refill the engine with the manufacturer-recommended oil type and quantity.

3. Inspect and Replace Oil Pressure Sensor

Sub-steps:
1. Locate the oil pressure sensor, usually near the oil filter.
2. Disconnect the electrical connector from the sensor.
3. Remove the sensor using a socket wrench.
4. Install the new oil pressure sensor and reconnect the electrical connector.

4. Repair or Replace Oil Pump (if required)

Sub-steps:
1. If low oil pressure persists after sensor replacement, inspect the oil pump.
