Solution

1. Preparation

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

2. Check and Top Off Engine Oil

Locate the oil filler cap and remove it.
Use a funnel to add the recommended oil type (refer to owner's manual) if the oil level is low.
Replace the oil filler cap securely.

3. Inspect and Replace Oil Pressure Sending Unit

Locate the oil pressure sending unit (typically near the oil filter).
Disconnect the electrical connector from the sending unit.
Use a socket to remove the sending unit from the engine block.
Install a new oil pressure sending unit and tighten it to the manufacturer's torque specifications (usually around 15-20 Nm).
Reconnect the electrical connector.

4. Replace Engine Oil and Oil Filter

Place the vehicle on jack stands and remove the oil drain plug.
Allow the old oil to completely drain into a pan.
Remove and replace the oil filter using an oil filter wrench.
Install the new oil filter and tighten it according to specifications.
Reinstall the oil drain plug and tighten it to the recommended torque (usually around 30-40 Nm).
Fill the engine with the recommended oil type through the oil filler cap.

5. Reconnect Battery and Test

Reconnect the battery terminals.
Start the engine and let it idle for a few minutes.
Check for oil leaks around the oil pressure sending unit and oil filter.
Monitor the oil pressure warning light; it should turn off after a few seconds.
