Solution

1. Preparation

Gather Tools and Parts: OBD-II scanner, mechanical oil pressure gauge, socket set, torque wrench, oil filter wrench, replacement oil and filter (if needed), safety glasses, and gloves.
Safety: Ensure the vehicle is parked on a level surface, and the engine is cool before starting any work.

2. Check Engine Oil Level

Remove the dipstick, clean it with a cloth, and reinsert it.
Pull it out again to check the oil level. If low, add the manufacturer-recommended oil.

3. Inspect for Leaks

Visually inspect the engine for any signs of oil leaks around the oil filter and oil pan.
Clean any debris around the oil filter and oil pan before proceeding.

4. Test Oil Pressure

Remove the oil pressure sending unit: Use a socket set to carefully remove the sending unit.
Install mechanical oil pressure gauge: Thread the gauge into the same location where the sending unit was removed.
Start the engine and observe the oil pressure reading; it should be within manufacturer specifications (typically between 25-60 psi at idle).

5. Replace Oil Filter and Oil (if necessary)

Drain old oil: Remove the drain plug from the oil pan and allow the oil to drain completely.
Remove old oil filter: Use an oil filter wrench to remove the old filter.
Install new oil filter: Apply a small amount of oil to the rubber seal of the new filter, then install it hand-tight.
Reinstall drain plug: Replace the drain plug and torque to manufacturer specifications.
Add new oil: Pour in the recommended type and amount of oil as specified in the owner's manual.

6. Verify Oil Pressure Sending Unit

If oil pressure is low, replace the oil pressure sending unit with a new one.
Reconnect any electrical connectors and ensure they are secure.
