Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a flat surface, engage the parking brake, and allow the engine to cool.

2. Change Engine Oil and Filter

Sub-steps:
- Drain the old engine oil using a socket set to remove the drain plug.
- Replace the oil filter using an oil filter wrench.
- Reinstall the drain plug and tighten it to the manufacturer's specified torque (usually around 25-30 lb-ft).
- Refill the engine with new oil of the correct type and viscosity (as per owner's manual).
- Start the engine and let it run for a few minutes, then check for leaks.

3. Replace Oil Pressure Sending Unit (if faulty)

Sub-steps:
- Locate the oil pressure sending unit (typically near the oil filter).
- Disconnect the electrical connector from the sending unit.
- Use a wrench to unscrew the faulty sending unit.
- Install the new oil pressure sending unit and connect the electrical connector.
- Ensure it is securely tightened (usually around 15-20 lb-ft).

4. Repair Oil Leaks (if present)

Sub-steps:
- Identify the source of the leaks (valve cover gaskets, oil pan gaskets, etc.).
- Remove the affected components to access the leaking gaskets.
- Clean the mating surfaces to ensure proper sealing.
- Replace old gaskets with new ones and reinstall components.
- Tighten all fasteners to specified torque settings.
