Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool and parked on a level surface.
Disconnect the negative battery terminal for safety.

2. Change Engine Oil and Filter

Tools Required: Socket set, oil filter wrench, oil catch pan.
Sub-steps:
1. Place an oil catch pan under the oil pan.
2. Remove the oil drain plug and allow the old oil to completely drain.
3. Replace the oil drain plug and torque it to manufacturer specifications (usually around 20 lb-ft).
4. Use an oil filter wrench to remove the old oil filter.
5. Apply a thin layer of new oil to the rubber gasket of the new oil filter and install it.
6. Fill the engine with the recommended type and amount of new oil (usually 5W-20 or 0W-20, check owner's manual for specifics).

3. Inspect and Replace Oil Pressure Sending Unit

Tools Required: Socket set, torque wrench.
Sub-steps:
1. Locate the oil pressure sending unit (usually near the oil filter).
2. Disconnect the electrical connector from the oil pressure sending unit.
3. Use a socket to remove the oil pressure sending unit.
4. Install the new oil pressure sending unit and torque it to specifications (typically around 15 lb-ft).
5. Reconnect the electrical connector.

4. Test Oil Pressure

Tools Required: Mechanical oil pressure gauge.
Sub-steps:
1. Remove the oil pressure sending unit and install the mechanical oil pressure gauge.
2. Start the engine and observe the oil pressure reading; it should be within the manufacturer's specified range (usually 20-60 psi at idle).
3. If the pressure is low, further investigation may be required for internal engine issues.
