Solution

1. Preparation

Tools Required: Socket set, ratchet, oil pressure gauge, OBD-II scanner, torque wrench, oil catch pan.
Allow the engine to cool before beginning the repair.
Disconnect the battery to ensure safety.

2. Check and Change Oil

Sub-steps:
1. Remove the oil drain plug using a socket wrench and let the old oil drain into the catch pan.
2. Replace the oil filter using an oil filter wrench.
3. Install a new oil filter and ensure it is tight.
4. Replace the drain plug and torque it to manufacturer's specifications (usually around 20 lb-ft).
5. Refill the engine with the appropriate oil grade (typically 5W-20) to the correct level.

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 unscrew the unit using a socket wrench.
3. Apply a small amount of thread sealant to the threads of the new sending unit.
4. Screw in the new unit and reconnect the electrical connector.

4. Test Oil Pressure

Sub-steps:
1. Remove the oil pressure sending unit.
2. Install the mechanical oil pressure gauge in its place.
3. Start the engine and monitor the oil pressure reading on the gauge.
4. If readings are low, further investigate the oil pump or internal engine issues.
