Solution

1. Preparation

Tools Required:
- OBD-II scanner
- Oil pressure gauge
- Socket set
- Torque wrench
- Oil filter wrench
Ensure the engine is cool and parked on a level surface.

2. Check and Replace Engine Oil

Sub-steps:
1. Remove the oil filler cap and check the oil level on the dipstick.
2. If the oil level is low, add the recommended oil type (SAE 0W-20 for most RAV4 models).
3. If oil is contaminated, drain the old oil using an oil drain pan.
4. Replace with new oil, ensuring to fill to the correct level.

3. Replace Oil Filter

Sub-steps:
1. Use an oil filter wrench to remove the old oil filter.
2. Apply a small amount of new oil to the rubber gasket of the new filter.
3. Install the new oil filter, tightening it according to manufacturer specifications (typically hand-tight).

4. Inspect and Replace 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 the new sending unit and reconnect the electrical connector.

5. Test Oil Pressure

Sub-steps:
1. Install an oil pressure gauge in place of the sending unit.
2. Start the engine and monitor the oil pressure readings.
3. If the pressure is below specifications (consult service manual), the oil pump may need to be replaced.
