Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical issues.

2. Check and Replace Engine Oil

Sub-steps:
1. Remove the oil drain plug using a socket wrench and drain the old oil into a container.
2. Replace the oil filter if it is found to be clogged or damaged.
3. Install a new oil filter by applying a small amount of oil to the gasket and tightening it to manufacturer specifications.
4. Replace the drain plug and torque it to the specified value (typically around 30 ft-lbs).
5. Fill the engine with the recommended oil type (typically 0W-20 or 5W-20) and check the level with the dipstick.

3. Inspect and Replace Oil Pressure Sensor

Sub-steps:
1. Locate the oil pressure sensor, usually found near the oil filter.
2. Disconnect the electrical connector from the sensor.
3. Remove the oil pressure sensor using a socket.
4. Install the new oil pressure sensor and torque it to the manufacturer specifications.
5. Reconnect the electrical connector.

4. Clear Codes and Test

Sub-steps:
1. Reconnect the negative battery terminal.
2. Use the OBD-II scanner to clear any error codes.
3. Start the engine and monitor oil pressure warning light.
4. Allow the engine to idle and check for any abnormal noises or leaks.
