Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Change Engine Oil and Filter

Sub-steps:
- Place an oil drain 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 with a new washer and torque it to the manufacturer's specifications (typically around 25 Nm).
- Remove the old oil filter using an oil filter wrench, applying oil to the rubber gasket of the new filter.
- Install the new oil filter, hand-tightening it to avoid leaks.
- Fill the engine with the recommended type and amount of oil (usually 5W-30 or as specified in the owner's manual).

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

Sub-steps:
- Locate the oil pressure sending unit on the engine (usually near the oil filter).
- Disconnect the electrical connector gently.
- Use a socket wrench to remove the sending unit.
- Install the new sending unit and torque it to the specified value.
- Reconnect the electrical connector.

4. Check Oil Pump Operation (if necessary)

Sub-steps:
- If oil pressure is still low, remove the oil pump from the engine (this may require access through the oil pan).
- Inspect the pump for wear or damage.
- Replace the oil pump if needed, following manufacturer specifications for installation and torque values.
