Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the engine is cool and the vehicle is parked on a level surface.
Disconnect the negative battery terminal to prevent electrical shock.

2. Check and Replace Engine Oil

Sub-step 1: Remove the oil filler cap and check the oil level with a dipstick.
Sub-step 2: If low, add the appropriate grade of oil as specified in the owner's manual.
Sub-step 3: If oil is dirty or overdue for a change, proceed to replace the oil.
Tools Required: Socket set, oil filter wrench, oil catch pan.

3. Inspect and Replace Oil Filter

Sub-step 1: Locate the oil filter and remove it using the oil filter wrench.
Sub-step 2: Apply a thin layer of fresh oil to the rubber gasket of the new filter.
Sub-step 3: Install the new oil filter, ensuring it is securely tightened but not over-torqued.
Tools Required: Oil filter wrench, socket set.

4. Test Oil Pressure

Sub-step 1: Remove the oil pressure sending unit using a socket.
Sub-step 2: Install a mechanical oil pressure gauge in its place.
Sub-step 3: Start the engine and observe the pressure reading. It should be within the manufacturer's specifications (typically 25-65 psi at idle).
Tools Required: Mechanical oil pressure gauge, socket set.

5. Inspect Oil Pump

Sub-step 1: If oil pressure is low, inspect the oil pump for signs of wear or damage.
Sub-step 2: Remove the oil pan to access the oil pump if necessary.
Sub-step 3: Replace the oil pump if it is found to be faulty.
Tools Required: Torque wrench, socket set, oil pan gasket.
