Solution

1. Preparation

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

2. Check and Add Oil

Remove the oil fill cap.
Use a funnel to add the appropriate type and amount of oil (refer to the owner's manual for specifications).
Replace the oil fill cap securely.

3. Replace Oil Pressure Sending Unit (if faulty)

Locate the oil pressure sending unit (usually near the oil filter).
Use a socket wrench to disconnect the electrical connector.
Unscrew the sending unit using a suitable socket.
Install the new sending unit by reversing the removal process, ensuring it’s tightened to manufacturer specifications (typically around 15 Nm).
Reconnect the electrical connector.

4. Change Engine Oil and Filter

Drain the old engine oil by removing the oil drain plug (ensure a container is underneath).
Replace the oil filter using an oil filter wrench; lubricate the rubber O-ring on the new filter before installation.
Reinstall the oil drain plug and tighten to the specified torque (usually around 25 Nm).
Fill the engine with the correct type of oil through the oil fill cap.

5. Check Oil Pump (if necessary)

If oil pressure is still low, remove the oil pump.
Inspect for wear, damage, or blockage.
Replace with a new oil pump if necessary, following the manufacturer's specifications for installation.
