Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical issues during repairs.

2. Change Engine Oil and Filter

Sub-steps:
- Place an oil catch pan under the oil pan.
- Remove the oil drain plug using a socket wrench and let the old oil drain completely.
- Replace the oil drain plug and torque it to the manufacturer's specification (typically around 20-30 Nm).
- Remove the old oil filter using an oil filter wrench. Lubricate the rubber gasket of the new filter with fresh oil and install it.
- Fill the engine with the recommended oil type (usually 5W-30 or 0W-40 for this model) using a funnel, ensuring to add the correct volume (around 4.5 liters).

3. Inspect and Replace Oil Pressure Sending Unit

Sub-steps:
- Locate the oil pressure sending unit, typically near the oil filter or on the engine block.
- Disconnect the electrical connector and unscrew the sending unit using a socket.
- Install the new oil pressure sending unit and reconnect the electrical connector.

4. Inspect and Replace the Oil Pump (if necessary)

Sub-steps:
- Remove the oil pan by taking off the bolts with a socket set. Be prepared for some oil to spill.
- Inspect the oil pump for any wear or damage; if necessary, remove it by unscrewing the mounting bolts.
- Install the new oil pump, ensuring it’s properly aligned and secured.
- Reinstall the oil pan with a new gasket, ensuring it is tightened to the specified torque.
