Solution

1. Preparation

Tools Required:
- OBD-II scanner
- Oil pressure gauge
- Socket set
- Oil filter wrench
- Drain pan
Safety Warnings:
- Allow the engine to cool before starting any work.
- Disconnect the battery to prevent electrical shorts.

2. Change Engine Oil and Filter

Sub-steps:
1. Drain Old Oil: Place a drain pan under the oil pan, remove the drain plug, and let the old oil drain completely.
2. Remove Oil Filter: Use an oil filter wrench to remove the old oil filter. Make sure the rubber gasket comes off with the filter.
3. Install New Oil Filter: Apply a thin layer of new oil to the gasket of the new filter. Screw it into place by hand until snug.
4. Replace Drain Plug: Reinstall and torque the drain plug to the manufacturer's specifications (typically around 30 ft-lbs).
5. Add New Oil: Pour the correct type and amount of new oil into the engine (check owner's manual for specifications).
6. Check for Leaks: Start the engine and let it run for a few minutes. Inspect for any leaks around the filter and drain plug.

3. Replace Oil Pressure Sensor (if necessary)

Sub-steps:
1. Locate the Oil Pressure Sensor: Identify the sensor, typically located near the oil filter.
2. Disconnect Wiring Harness: Carefully disconnect the electrical connector from the sensor.
3. Remove Old Sensor: Use a wrench to unscrew the old oil pressure sensor.
4. Install New Sensor: Thread in the new sensor and tighten it to the manufacturer's torque specification.
5. Reconnect Wiring: Reattach the electrical connector to the new oil pressure sensor.
