Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and the engine is turned off and cool.
Disconnect the battery to prevent any electrical issues.

2. Check and Replace Engine Oil

Remove the oil filler cap.
Using a socket set, remove the oil drain plug and allow the old oil to drain into a pan.
Replace the oil filter using an oil filter wrench; lubricate the rubber gasket on the new filter with fresh oil before installation.
Reinstall the oil drain plug and torque it to the manufacturer's specification (usually around 30 lb-ft).
Add the correct type and amount of new engine oil (typically 0W-20 for this model) through the oil filler neck.

3. Inspect and Replace the Oil Pressure Sending Unit

Locate the oil pressure sending unit, usually near the oil filter on the engine block.
Disconnect the electrical connector from the sending unit.
Remove the sending unit using a wrench; be cautious to catch any oil that may spill.
Install the new oil pressure sending unit and tighten it to specification.
Reconnect the electrical connector.

4. Final Checks

Reconnect the battery.
Start the engine and allow it to run for a few minutes.
Check for any leaks around the oil drain plug and oil filter.
Monitor the oil pressure warning light; it should extinguish if the issue is resolved.
