Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is cool.
Gather necessary tools and parts.
Wear safety gloves and goggles.

2. Change Engine Oil

Sub-steps:
1. Use a wrench to remove the drain plug from the oil pan and allow old oil to drain completely into a suitable container.
2. Replace the drain plug and tighten it to the manufacturer's torque specification (typically around 20-25 lb-ft).
3. Remove the old oil filter using an oil filter wrench.
4. Apply a thin layer of new oil to the rubber gasket of the new oil filter.
5. Install the new oil filter by hand until snug, then tighten it an additional 3/4 turn.

3. Replace Oil Pressure Sending Unit (if necessary)

Sub-steps:
1. Disconnect the electrical connector from the oil pressure sending unit.
2. Remove the sending unit using a socket (usually 1-inch or 3/8-inch drive).
3. Install the new sending unit and tighten it to the specified torque (approximately 15-20 lb-ft).
4. Reconnect the electrical connector securely.

4. Test Oil Pressure

Sub-steps:
1. Attach an external oil pressure gauge to the oil pressure sending unit's port.
2. Start the engine and observe the oil pressure reading on the gauge.
3. If the reading is below the manufacturer's recommended range (typically 25-60 psi at idle), further investigation into the oil pump or internal engine issues may be needed.

5. Refill Engine Oil

Sub-steps:
1. Open the hood and remove the oil filler cap.
2. Pour in the recommended type and amount of new engine oil (typically 5W-20 or 0W-20).
3. Start the engine and let it run for a few minutes.
4. Check the oil level again using the dipstick and add oil if necessary.
