Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid electrical hazards.

2. Check and Top Off 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 oil (5W-20 or as specified by the manufacturer) until the level is correct.

3. Replace Oil Filter

Locate the oil filter. Use an 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 by hand, tightening it according to manufacturer specifications (typically hand-tight plus a quarter turn).

4. Change Engine Oil

Drain the old oil by removing the oil drain plug with a socket set. Allow it to fully drain into an oil pan.
Replace the drain plug (tighten to manufacturer specifications).
Pour in the new engine oil through the oil filler neck using a funnel.

5. Replace Oil Pressure Sending Unit

Locate the oil pressure sending unit (usually near the oil filter).
Disconnect the electrical connector.
Use a socket to remove the sending unit and replace it with a new unit, tightening it as specified.
Reconnect the electrical connector.

6. Reconnect Battery and Test

Reconnect the battery.
Start the engine and monitor the oil pressure warning light.
Check for leaks around the oil filter and oil pressure sending unit.
