Solution

1. Preparation

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

2. Change Engine Oil and Filter

Sub-steps:
1. Place an oil catch pan under the oil pan.
2. Remove the drain plug using a socket set and allow old oil to drain completely.
3. Replace the drain plug and torque to manufacturer specifications (usually around 30 ft-lbs).
4. Remove the old oil filter using an oil filter wrench.
5. Apply a thin layer of new oil to the rubber gasket of the new oil filter.
6. Install the new oil filter and tighten it according to specifications (usually hand-tight plus a quarter turn).
7. Fill the engine with new oil (consult owner's manual for the correct oil type and capacity, typically 0W-20 or 5W-20).

3. Replace the Oil Pressure Sending Unit (if faulty)

Sub-steps:
1. Locate the oil pressure sending unit (usually near the oil filter).
2. Disconnect the electrical connector.
3. Use a socket to remove the old sending unit.
4. Install the new sending unit and torque it to specifications (typically 15 ft-lbs).
5. Reconnect the electrical connector.

4. Inspect and Replace Oil Pump (if necessary)

Sub-steps:
1. Remove the oil pan by loosening the bolts with a socket set.
2. Carefully detach the oil pan and clean the gasket surface.
3. Remove the oil pump from its mounting location.
4. Install the new oil pump and torque the bolts to specifications (check service manual for values).
5. Reattach the oil pan with a new gasket and torque the bolts evenly.
