Solution

1. Preparation

Ensure the vehicle is on a level surface and the engine is cool.
Gather tools: oil pressure gauge, socket set, oil filter wrench, new oil, and oil filter.

2. Check Oil Level

Open the hood and locate the dipstick.
Pull the dipstick out, wipe it clean, and reinsert it fully.
Remove it again to check the oil level; add oil if necessary.

3. Inspect for Leaks

Visually inspect the oil pan, oil filter, and engine seals for any oil leaks.
Clean any dirty areas to identify fresh leaks easily.

4. Test Oil Pressure

Remove the oil pressure sending unit using the appropriate socket.
Install the oil pressure gauge in place of the sending unit.
Start the engine and observe the oil pressure reading on the gauge; it should be within the manufacturer's specifications (typically between 20-60 psi at idle).

5. Replace Oil Filter (if necessary)

If the filter is clogged or damaged, remove it using the oil filter wrench.
Install a new oil filter according to the manufacturer's specifications, ensuring the rubber O-ring is properly seated.

6. Replace or Repair Oil Pump (if necessary)

If oil pressure is still low, you may need to access and replace the oil pump.
Disconnect the negative battery terminal.
Drain the engine oil and remove the oil pan to access the oil pump.
Remove the old oil pump and install the new one, following the manufacturer's torque specifications for the oil pan bolts.
