Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, mechanical oil pressure gauge, oil filter wrench, and clean rags.
Ensure the vehicle is parked on a level surface and the engine is cool before starting work.

2. Check and Top Off Engine Oil

Sub-steps:
1. Open the hood and locate the engine oil dipstick.
2. Pull out the dipstick, clean it with a rag, and reinsert it fully.
3. Remove the dipstick again and check the oil level. If low, add the manufacturer-recommended oil type until it reaches the full mark on the dipstick.
4. Start the engine and allow it to run for a minute, then check the oil level again, topping off as necessary.

3. Replace Oil Filter

Sub-steps:
1. Locate the oil filter and use an oil filter wrench to remove it.
2. Apply a thin layer of new oil on the rubber gasket of the new oil filter.
3. Install the new oil filter, hand-tighten it, and follow up with a torque wrench to the manufacturer's specifications (typically around 25 Nm or 18 lb-ft).
4. Check for leaks after starting the engine.

4. Test Oil Pressure

Sub-steps:
1. Locate the oil pressure sending unit, usually near the oil filter or engine block.
2. Carefully disconnect the electrical connector from the sending unit.
3. Using a mechanical oil pressure gauge, replace the sending unit with the gauge.
4. Start the engine and observe the oil pressure reading; it should be within the manufacturer’s specified range (typically 20-60 psi at idle).
5. If readings are lower than expected, the oil pump may need replacement.

5. Repair or Replace Oil Pump (if necessary)

Sub-steps:
1. Disconnect the battery to avoid electrical shorts.
2. Drain the engine oil and remove the oil pan by unscrewing the bolts.
3. Remove the old oil pump, which is typically located near the oil pan.
4. Install the new oil pump and replace the oil pan with a new gasket, tightening bolts to the specified torque.
5. Refill the engine with fresh oil and reconnect the battery.
