Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off and cooled down.

2. Check and Top Off Oil Level

Tools Required: Oil dipstick, funnel, appropriate 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 appropriate engine oil through the oil filler cap using a funnel.

3. Replace Oil Filter (if clogged)

Tools Required: Oil filter wrench, oil catch pan, new oil filter
Place the oil catch pan under the oil filter.
Use the oil filter wrench to remove the old oil filter.
Apply a little new oil to the rubber gasket of the new filter.
Install the new oil filter, tightening it by hand until snug.

4. Inspect and Replace Oil Pressure Sending Unit (if faulty)

Tools Required: Socket set, torque wrench
Locate the oil pressure sending unit (usually near the oil filter).
Disconnect the electrical connector from the sending unit.
Use a socket to remove the old sending unit.
Install the new sending unit and torque it to the manufacturer's specifications (check service manual for exact torque values).
Reconnect the electrical connector.

5. Test Oil Pressure

Tools Required: Mechanical oil pressure gauge
Remove the oil pressure sending unit and install the mechanical oil pressure gauge.
Start the engine and check the oil pressure reading. It should be within the manufacturer's specifications (typically 20-60 psi at idle, depending on engine temperature).
If pressure is low, consider further inspection of the oil pump.
