Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to avoid electrical shorts.

2. Change Engine Oil and Filter

Sub-steps:
1. Place an oil catch pan under the oil pan.
2. Remove the oil drain plug with a socket set (typically 17mm) and allow the oil to drain completely.
3. Replace the drain plug with a new washer and torque it to manufacturer specifications (typically 30 lb-ft).
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 and install it.
6. Fill the engine with the recommended oil (typically 0W-20) through the oil filler cap, using a funnel.
7. Start the engine and let it run for a few minutes while checking for leaks.

3. Replace Oil Pressure Sending Unit (if faulty)

Sub-steps:
1. Locate the oil pressure sending unit, usually near the oil filter or on the engine block.
2. Disconnect the electrical connector from the sending unit.
3. Use a socket to unscrew the sending unit from the engine.
4. Install the new oil pressure sending unit and torque it to manufacturer specifications (usually around 15 lb-ft).
5. Reconnect the electrical connector.

4. Verify Oil Pressure

Sub-steps:
1. Remove the oil pressure sending unit again.
2. Install an oil pressure gauge in place of the sending unit.
3. Start the engine and check the oil pressure reading; it should be within the manufacturer's specified range (typically 20-60 psi at idle).
4. If the pressure is low, further investigation of the oil pump or internal engine components may be necessary.
