Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to avoid any electrical issues during repairs.

2. Inspect and Replace Oil

Sub-steps:
1. Remove the drain plug using a socket set to drain the old oil into a suitable container.
2. Replace the drain plug with a new washer and torque it to the manufacturer’s specifications (typically around 25 Nm).
3. Remove the oil filter using an oil filter wrench and prepare to install a new one.
4. Lubricate the rubber gasket on the new oil filter with fresh engine oil.
5. Install the new oil filter and tighten it by hand until snug, then tighten an additional 3/4 turn.
6. Fill the engine with the correct type of oil (typically 5W-30 or 0W-40 depending on the engine variant) using a funnel.

3. Replace Oil Pressure Sensor

Sub-steps:
1. Locate the oil pressure sensor, typically near the oil filter or on the oil filter housing.
2. Disconnect the electrical connector from the oil pressure sensor.
3. Use a socket wrench to remove the old oil pressure sensor.
4. Install the new sensor and torque it to the manufacturer’s specifications (usually around 20 Nm).
5. Reconnect the electrical connector securely.

4. Verification

Reconnect the battery and start the engine.
Allow the engine to idle and monitor the oil pressure warning light.
Check for any leaks around the oil filter and oil pressure sensor.
Test drive the vehicle to ensure the issue is resolved and observe for any abnormal noises.
