Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a level surface.
Ensure the engine is cool before beginning work.
Tools Required: Oil dipstick, OBD-II scanner, mechanical oil pressure gauge, socket set.

2. Check and Top Off Engine Oil

Open the hood and locate the oil dipstick.
Remove the dipstick, wipe it clean with a cloth, and reinsert it fully.
Remove the dipstick again to check the oil level; it should be between the "low" and "full" marks.
If the oil level is low, add the appropriate type of oil (refer to the owner's manual for specifications).
Recheck the level after adding oil and ensure it is within the acceptable range.

3. Inspect Oil Pressure Sending Unit

Locate the oil pressure sending unit (usually found near the oil filter).
Disconnect the electrical connector from the sending unit.
Using a socket, remove the sending unit from the engine.
Install a mechanical oil pressure gauge in place of the sending unit.
Start the engine and read the oil pressure; it should meet manufacturer specifications (typically 25-65 PSI when warm).
If pressure is low, further inspection of the oil pump and engine internals may be necessary.

4. Replace Oil Filter (if necessary)

If the oil is dirty or the filter is clogged, replace the oil filter.
Use an oil filter wrench to remove the old filter.
Apply a thin layer of new oil to the rubber gasket of the new filter.
Install the new filter and tighten it according to the manufacturer’s specifications (usually hand-tight).
Fill the engine with the appropriate amount of new oil.
