Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is cold.
Gather tools: socket set, oil filter wrench, and oil catch pan.

2. Check and Replace Engine Oil

Sub-step 1: Remove the oil fill cap and inspect oil condition.
Sub-step 2: If oil level is low, drain old oil using an oil catch pan.
Sub-step 3: Replace with new engine oil according to manufacturer specifications (e.g., 5W-30).
Sub-step 4: Reinstall the oil fill cap.

3. Replace Oil Filter

Sub-step 1: Use an oil filter wrench to remove the old oil filter.
Sub-step 2: Apply a small amount of new oil to the rubber gasket of the new oil filter.
Sub-step 3: Install the new oil filter, hand-tightening it securely.

4. Inspect and Replace Oil Pressure Sensor

Sub-step 1: Locate the oil pressure sensor; it is usually near the oil filter.
Sub-step 2: Disconnect the electrical connector from the sensor.
Sub-step 3: Use a socket set to remove the old sensor.
Sub-step 4: Install the new oil pressure sensor and reconnect the electrical connector.

5. Final Checks

Sub-step 1: Start the engine and let it idle for a few minutes.
Sub-step 2: Monitor the oil pressure warning light to ensure it has turned off.
Sub-step 3: Check for leaks around the oil filter and oil pressure sensor.
