Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.

2. Change Engine Oil and Filter

Sub-steps:
1. Drain Old Oil:
  - Place an oil drain pan under the oil pan.
  - Remove the drain plug using a socket wrench and allow oil to fully drain.
2. Replace Oil Filter:
  - Use an oil filter wrench to remove the old oil filter.
  - Lubricate the rubber O-ring of the new oil filter with fresh oil and install it hand-tight.
3. Refill Engine Oil:
  - Replace the drain plug and tighten it to the manufacturer’s torque specifications (typically around 20-25 lb-ft).
  - Pour in the recommended type and amount of new oil (5W-30 synthetic is commonly used).

3. Replace Oil Pressure Sending Unit

Sub-steps:
1. Locate the oil pressure sending unit on the engine block.
2. Disconnect the electrical connector from the unit.
3. Use a socket wrench to remove the sending unit.
4. Install the new sending unit, tightening it to the specified torque (usually 15-20 lb-ft).
5. Reconnect the electrical connector.

4. Inspect Oil Pump (if necessary)

Sub-steps:
1. Remove the oil pan by unbolting it and carefully lowering it.
2. Inspect the oil pump for any visible damage or wear.
3. If the pump is faulty, replace it with a new unit, following the manufacturer’s specifications for installation.
