Solution

1. Preparation

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

2. Drain Engine Oil

Place an oil drain pan under the oil pan.
Remove the oil drain plug using a socket wrench.
Allow the oil to fully drain into the pan.

3. Replace Oil Filter

Locate the oil filter (usually accessible from the bottom of the engine).
Use an oil filter wrench to remove the old oil filter.
Prepare the new oil filter by applying a small amount of new oil to the rubber O-ring.
Install the new oil filter by hand, tightening it according to the manufacturer's specifications.

4. Replace Engine Oil

Reinstall the oil drain plug and tighten it to the specified torque (usually around 25 Nm, but verify according to manufacturer specs).
Fill the engine with the correct type and amount of oil (typically 5W-30 or 0W-40, depending on the engine variant).
Start the engine and let it run for a few minutes, then check for any leaks around the oil filter and drain plug.

5. Check Oil Pressure Sending Unit

Locate the oil pressure sending unit on the engine (usually near the oil filter).
Disconnect the electrical connector from the sending unit.
Remove the sending unit using a wrench and replace it with a new one, ensuring it is tightened securely.
Reconnect the electrical connector.
