Solution

1. Preparation

Tools Required: Wrench set, oil pressure gauge, OBD-II scanner, oil catch pan, cleaning materials.
Ensure the engine is off and cool. Disconnect the battery to prevent any electrical issues while working on the vehicle.

2. Change Engine Oil and Filter

Sub-steps:
1. Place the oil catch pan under the oil pan.
2. Remove the oil drain plug using the appropriate wrench and allow the old oil to drain completely.
3. Replace the oil drain plug and torque it to the manufacturer specifications (typically around 30 ft-lb).
4. Remove the old oil filter using an oil filter wrench.
5. Lubricate the rubber O-ring on the new oil filter with a bit of new oil, then install the new filter by hand until snug.
6. Fill the engine with the recommended oil type and capacity (typically 0W-20 or 5W-20 for Camry) using a funnel.

3. Replace Oil Pressure Sending Unit

Sub-steps:
1. Locate the oil pressure sending unit, which is typically found near the oil filter.
2. Disconnect the electrical connector from the sending unit.
3. Using a wrench, remove the old oil pressure sending unit.
4. Install the new oil pressure sending unit and torque it to specifications.
5. Reconnect the electrical connector.

4. Test Oil Pressure

Sub-steps:
1. Install an external oil pressure gauge in place of the oil pressure sending unit.
2. Start the engine and monitor the gauge for oil pressure readings.
3. If pressure is within specifications (typically 10-20 psi at idle and 25-40 psi at 2000 RPM), the system is functioning correctly; if not, further investigation of the oil pump may be needed.
