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 to avoid any electrical shorts.

2. Replace Engine Oil

Sub-steps:
1. Drain the old engine oil by removing the drain plug and allowing it to fully drain into a pan.
2. Replace the drain plug and tighten it to the manufacturer’s specified torque (usually around 30 lb-ft).
3. Remove the old oil filter using an oil filter wrench.
4. Lubricate the rubber O-ring on the new oil filter with fresh oil and install the new filter, tightening by hand.

3. Add New Engine Oil

Sub-steps:
1. Remove the oil filler cap and pour in the recommended type and amount of new engine oil (check the owner's manual for specifications).
2. Replace the oil filler cap securely.

4. Check Oil Pressure

Sub-steps:
1. Reconnect the battery.
2. Start the engine and let it idle while monitoring the oil pressure gauge.
3. If oil pressure is still low, further investigate the oil pump and oil pressure sending unit.
