Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to avoid electrical issues.

2. Check and Top Up Engine Oil

Remove the oil dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the oil level.
If low, add the appropriate type and viscosity of oil as specified in the owner’s manual.

3. Replace Oil Filter

Use an oil filter wrench to remove the old oil filter.
Apply a small amount of new oil to the rubber gasket of the new filter.
Install the new oil filter by hand until snug, then tighten it according to the manufacturer’s specifications.

4. Inspect and Replace Oil Pressure Sending Unit

Locate the oil pressure sending unit, usually near the oil filter.
Disconnect the electrical connector and remove the unit using a socket set.
Install the new oil pressure sending unit and reconnect the electrical connector.

5. Oil Pump Inspection/Replacement (if necessary)

If low oil pressure persists, remove the oil pan by draining the oil and unbolting the pan.
Inspect the oil pump for wear or damage.
Replace the oil pump if it is malfunctioning, following the manufacturer’s specifications for installation.
