Solution

1. Preparation

Gather tools and parts. Ensure the vehicle is parked on a level surface and the engine is cool.
Tools required: socket set, wrench set, OBD-II scanner, mechanical oil pressure gauge, oil filter wrench, oil catch pan.

2. Check and Add Engine Oil

Sub-steps:
1. Remove the dipstick, clean it with a cloth, and reinsert it to check the oil level.
2. If the oil level is low, remove the oil filler cap and add the appropriate type of oil as specified in the owner's manual.
3. Recheck the oil level after adding oil.

3. Inspect for Leaks

Sub-steps:
1. Visually inspect the engine and oil pan for any signs of oil leaks.
2. Use a flashlight if necessary to see under the engine.
3. Clean any visible oil spots to monitor for future leaks.

4. Test Oil Pressure

Sub-steps:
1. Remove the oil pressure sending unit using the appropriate socket.
2. Install the mechanical oil pressure gauge in place of the sending unit.
3. Start the engine and observe the oil pressure reading on the gauge. It should be within the manufacturer’s specified range.

5. Replace Oil Pressure Sending Unit (if necessary)

Sub-steps:
1. If the oil pressure is low, turn off the engine and disconnect the electrical connector from the oil pressure sending unit.
2. Remove the sending unit using a socket.
3. Install the new sending unit and reconnect the electrical connector.
4. Recheck oil pressure with the gauge.

6. Change Engine Oil and Filter (if necessary)

Sub-steps:
1. If oil is dirty or of incorrect viscosity, drain the engine oil using an oil catch pan.
2. Replace the oil filter using the oil filter wrench.
3. Refill the engine with the correct type and amount of oil.
