Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Check and Change Engine Oil

Sub-steps:
1. Remove the oil drain plug using a socket set and drain the old oil into a container.
2. Replace the oil filter using an oil filter wrench to remove it.
3. Install a new oil filter, ensuring the rubber O-ring is lubricated and properly seated.
4. Reinstall the oil drain plug and tighten to the manufacturer's specifications (typically 30 ft-lbs).
5. Fill the engine with the appropriate type and amount of new engine oil (usually 5W-30 for most Camry models).

3. Inspect Oil Pressure Sending Unit

Sub-steps:
1. Locate the oil pressure sending unit (usually near the oil filter).
2. Disconnect the electrical connector and unscrew the sending unit using a socket.
3. Install a new oil pressure sending unit.
4. Reconnect the electrical connector.

4. Check Oil Pump

Sub-steps:
1. If oil pressure remains low, consider inspecting the oil pump.
2. Remove the oil pump (may require removing the oil pan).
3. Inspect for wear and ensure the pump gears are intact.
4. Replace the oil pump if it shows signs of damage or wear.

5. Reconnect Battery and Start Engine

Sub-steps:
1. Reconnect the battery terminals.
2. Start the engine and monitor oil pressure readings.
3. Check for any leaks around the oil filter and drain plug.
