Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical issues.
Allow the engine to cool before starting work.

2. Check and Replace Engine Oil

Tools Required: Socket set, oil filter wrench, oil catch pan
Drain the old oil using the oil catch pan by removing the oil drain plug. Allow the oil to completely drain.
Replace the oil filter using the oil filter wrench. Ensure the old gasket is removed.
Reinstall the oil drain plug and torque it to the manufacturer’s specifications (typically around 25-30 ft-lbs).
Refill the engine with the recommended oil type (usually 0W-20 for Toyota Corolla) until it reaches the proper level on the dipstick.

3. Inspect and Replace Oil Pressure Sending Unit (if necessary)

Tools Required: Socket set, torque wrench
Locate the oil pressure sending unit (usually near the oil filter or engine block).
Disconnect the electrical connector.
Remove the sending unit using the appropriate socket.
Install the new oil pressure sending unit and torque it to the specified value (check the service manual for the correct torque).
Reconnect the electrical connector.

4. Test and Check for Leaks

Reconnect the battery.
Start the engine and allow it to idle. Check for warning lights.
Inspect for any oil leaks around the oil drain plug and oil pressure sending unit.
