5. Lubricate the O-ring of the new oil filter with fresh oil and install it.
6. Fill the engine with the appropriate type and amount of new oil (typically 0W-20 for the Camry) using a funnel.

3. Replace Oil Pressure Sending Unit

Sub-steps:
1. Locate the oil pressure sending unit on the engine block.
2. Disconnect the electrical connector from the sending unit.
3. Use a socket to remove the old sending unit.
4. Install the new sending unit and tighten to manufacturer's specifications.
5. Reconnect the electrical connector.

4. Check for Leaks

Sub-steps:
1. Start the engine and let it run for a few minutes.
2. Inspect the area around the oil filter and oil pressure sending unit for leaks.
3. Check the oil level again and add oil if necessary.
