1. Place an oil catch pan under the oil filter.
2. Use the oil filter wrench to remove the old filter.
3. Apply oil to the rubber gasket of the new oil filter.
4. Install the new oil filter, tightening according to manufacturer specifications (usually hand-tight plus a quarter turn).

4. Inspect and Replace Oil Pressure Sensor (if faulty)

Tools Required: Socket set, torque wrench
Sub-steps:
1. Locate the oil pressure sensor (typically 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, tightening to the manufacturer's torque specification.
