Solution

1. Preparation

Gather necessary tools and parts: oil filter, engine oil, oil pressure gauge, socket set, torque wrench.
Ensure the vehicle is parked on a level surface, and the engine is cool.

2. Change Engine Oil and Filter

Drain Old Oil:
- Place an oil catch pan under the oil pan.
- Remove the oil drain plug using a socket wrench and allow the old oil to drain completely.
- Replace the drain plug and torque it to the manufacturer's specification (typically around 25-30 Nm).
Replace Oil Filter:
- Locate the oil filter and use an oil filter wrench to remove it.
- Rub a small amount of new oil on the rubber gasket of the new oil filter.
- Install the new oil filter by hand until snug, then tighten it according to the manufacturer's specifications.
Add New Engine Oil:
- Open the engine oil filler cap and pour in the recommended type and amount of engine oil (check owner's manual for specifics).
- Replace the oil filler cap securely.

3. Inspect and Replace Oil Pressure Sending Unit (if faulty)

Locate the Oil Pressure Sending Unit:
- Identify the oil pressure sending unit location, usually near the oil filter or on the engine block.
Remove Old Sending Unit:
- Disconnect any electrical connectors attached to the sending unit.
- Use a socket wrench to remove the sending unit.
Install New Sending Unit:
- Apply some thread sealant to the threads of the new sending unit.
- Install the new sending unit and torque it to the manufacturer's specification.
- Reconnect the electrical connector.
