Solution

1. Preparation

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

2. Check and Refill Engine Oil

Remove the dipstick, wipe it clean, and reinsert it to check the oil level.
If low, add the appropriate type and amount of engine oil as specified in the owner’s manual.

3. Replace Oil Filter (if necessary)

Use an oil filter wrench to remove the old oil filter.
Lubricate the rubber gasket of the new oil filter with fresh oil.
Install the new oil filter, hand-tightening it until snug.

4. Test Oil Pressure

Locate the oil pressure sending unit (usually near the oil filter).
Remove the electrical connector and unscrew the oil pressure sending unit.
Install the oil pressure gauge in place of the sending unit.
Start the engine and check the oil pressure reading on the gauge; it should be within the manufacturer's specifications.

5. Inspect and Replace Sending Unit (if needed)

If the oil pressure is low but the gauge is functioning, the sending unit may be faulty.
Unscrew the old sending unit and install the new one, ensuring it is tightened properly.
Reconnect the electrical connector.
