Solution

1. Preparation

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

2. Check and Top Off Engine Oil

Remove the oil filler cap.
Add the appropriate type and grade of oil as specified in the owner's manual.
Recheck the oil level with the dipstick and replace the cap.

3. Inspect and Replace Oil Filter

Locate the oil filter and use an oil filter wrench to remove it.
Check the filter for any signs of leakage or damage.
Apply a little new oil to the rubber gasket of the new oil filter.
Install the new oil filter by hand and tighten it according to the manufacturer's specifications.

4. Replace Oil Pressure Sending Unit

Locate the oil pressure sending unit, typically found near the oil filter.
Disconnect the electrical connector and unscrew the sending unit using a socket wrench.
Install the new oil pressure sending unit by screwing it in and reconnecting the electrical connector.

5. Flush Engine Oil (if necessary)

If the oil is contaminated, perform an engine oil flush following the product instructions.
Drain the old oil and replace it with new oil.

6. Reconnect Battery and Start Engine

Reconnect the battery terminals.
Start the engine and allow it to idle.
Monitor the oil pressure gauge and verify that the oil pressure warning light has turned off.
