Solution

1. Preparation

Tools Required: OBD-II scanner, mechanical oil pressure gauge, socket set, torque wrench, oil filter wrench.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Check and Top Up Engine Oil

Remove the dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the oil level.
If low, add the recommended engine oil type (refer to the owner's manual).
Start the engine and allow it to run for a few minutes, then recheck the oil level.

3. Inspect and Replace Oil Filter

Locate the oil filter and inspect for leaks or damage.
Use an oil filter wrench to remove the old oil filter.
Apply a thin layer of new oil to the rubber gasket of the new filter.
Install the new oil filter by hand until snug, then use the wrench to tighten it according to specifications.
Ensure no oil spills occur during the process.

4. Test Oil Pressure

Remove the oil pressure sending unit using a socket.
Install the mechanical oil pressure gauge in place of the sending unit.
Start the engine and observe the gauge reading; it should be within the manufacturer's specifications (usually around 20-60 psi at idle).
Turn off the engine and remove the gauge.

5. Replace Oil Pressure Sending Unit (if necessary)

If the oil pressure is low, and the gauge confirms it, replace the oil pressure sending unit.
Install the new sending unit by hand, then tighten it according to the torque specifications provided in the manual.
