Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off and cool.
Disconnect the battery for safety.

2. Check and Top Off Engine Oil

Remove the oil filler cap.
Using a funnel, add the appropriate engine oil if the level is low.
Replace the oil filler cap securely.

3. Inspect and Replace Oil Filter

Tools Required: Oil filter wrench, socket set
Using an oil filter wrench, remove the oil filter. Be prepared for some oil spillage.
Apply a thin layer of clean oil to the rubber seal of the new oil filter.
Install the new oil filter by hand until snug, then tighten further according to the manufacturer's specifications (usually 3/4 turn after contact).

4. Replace Oil Pressure Sending Unit (if faulty)

Locate the oil pressure sending unit, typically near the oil filter.
Disconnect the electrical connector from the sending unit.
Use a socket wrench to remove the old sending unit.
Install the new sending unit by threading it into place and tightening it securely.
Reconnect the electrical connector.

5. Check and Change Oil

Tools Required: Oil drain pan, socket set, funnel
Place an oil drain pan under the oil pan.
Remove the oil drain plug using a socket wrench and allow the old oil to drain completely.
Replace the oil drain plug and tighten it to the manufacturer’s torque specification.
Add the appropriate amount of new oil through the oil filler cap using a funnel.

6. Reconnect Battery and Test

Reconnect the battery terminals.
Start the engine and allow it to idle. Monitor the oil pressure warning light and listen for any abnormal sounds.
Check for leaks around the oil filter and drain plug.
