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 for safety.

2. Change Engine Oil

Sub-steps:
1. Place a drain pan beneath the oil pan.
2. Remove the oil drain plug with a socket set and allow oil to drain completely.
3. Replace the oil drain plug and tighten to the manufacturer's torque specification (usually around 20-25 ft-lbs).
4. Remove the old oil filter using an oil filter wrench.
5. Lubricate the rubber O-ring of the new oil filter with fresh oil and install it.

3. Replace Oil Pressure Sending Unit

Sub-steps:
1. Locate the oil pressure sending unit, usually near the oil filter.
2. Disconnect the electrical connector and remove the unit using a socket.
3. Install the new oil pressure sending unit and connect the electrical connector.

4. Inspect and Replace Oil Pump (if necessary)

Sub-steps:
1. Remove the oil pan by unbolting it from the engine block.
2. Take out the old oil pump, ensuring to note the orientation for the new pump.
3. Install the new oil pump, ensuring it is seated correctly, and bolt it in place.
4. Reinstall the oil pan and tighten bolts to specifications.

5. Refill Engine Oil

Sub-steps:
1. Refill the engine with the appropriate type and amount of oil as specified in the owner's manual.
2. Start the engine and let it idle for a few minutes while checking for leaks.
