Solution

1. Preparation

Gather tools and parts, ensuring the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check Engine Oil Level

Remove the dipstick, wipe it clean, reinsert it fully, and then remove it to check the oil level.
If low, add the appropriate type of oil (SAE 0W-20 or 5W-20) as specified in the owner's manual.

3. Replace Oil Filter

Use an oil filter wrench to remove the old filter.
Apply a thin layer of new oil on the rubber O-ring of the new filter.
Install the new filter by hand until snug, then tighten it an additional 3/4 turn.

4. Oil Change (if oil is dirty or low)

Drain the old oil using a socket wrench to remove the drain plug. Allow the oil to fully drain into a container.
Replace the drain plug, tightening to 30 ft-lbs torque specification.
Refill the engine with new oil through the oil filler cap.

5. Check and Replace Oil Pressure Sending Unit (if pressure is still low)

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

6. Final Check

Reconnect the negative battery terminal.
Start the engine and allow it to idle; observe the oil pressure light for any changes.
