Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface.
Disconnect the battery to prevent electrical shorts during repairs.

2. Check and Top Off Engine Oil

Sub-steps:
- Locate the engine oil filler cap; remove it.
- If the oil level is low (below the dipstick's minimum mark), add the appropriate type of oil (consult owner's manual for specifications).
- Replace the oil filler cap securely.

3. Replace Oil Pressure Sending Unit (if faulty)

Sub-steps:
- Locate the oil pressure sending unit (usually near the oil filter).
- Disconnect the electrical connector from the sending unit.
- Use a wrench to remove the old sending unit.
- Install the new oil pressure sending unit; tighten to manufacturer specifications (typically around 12-15 ft-lbs).
- Reconnect the electrical connector.

4. Change Engine Oil and Filter (if oil is degraded)

Sub-steps:
- Place an oil drain pan under the oil pan.
- Remove the oil drain plug using a socket wrench and allow old oil to drain completely.
- Replace the drain plug and tighten to manufacturer specifications (typically around 25 ft-lbs).
- Remove the old oil filter using an oil filter wrench. Lubricate the rubber gasket of the new filter with fresh oil, then install it.
- Pour the appropriate type and amount of new engine oil through the oil filler cap.
