Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues during repair.

2. Change Engine Oil and Filter

Sub-steps:
1. Place an oil catch pan under the oil pan.
2. Remove the oil drain plug using a socket wrench and allow the old oil to drain completely.
3. Replace the oil drain plug and torque to manufacturer specifications (typically around 30 ft-lbs).
4. Remove the old oil filter using an oil filter wrench.
5. Apply a small amount of new oil to the rubber gasket of the new oil filter.
6. Install the new oil filter and tighten by hand until snug.
7. Refill the engine with the manufacturer recommended oil type and capacity (usually 0W-20 for Camry).

3. Replace Oil Pressure Sending Unit

Sub-steps:
1. Locate the oil pressure sending unit (usually near the oil filter).
2. Disconnect the electrical connector from the sending unit.
3. Remove the sending unit using a socket or wrench.
4. Install the new sending unit and tighten to the manufacturer's torque specifications.
5. Reconnect the electrical connector.

4. Test Oil Pressure

Sub-steps:
1. Attach a mechanical oil pressure gauge to the engine’s oil pressure port.
2. Start the engine and observe the oil pressure readings; it should be within the manufacturer’s specified range (typically 25-65 psi at idle).
3. If the pressure is low, further investigation of the oil pump or internal engine components may be necessary.
